Connecting to Microsoft Power BI XMLA

To connect, set the Workspace property to a valid PowerBIXMLA workspace (ex: CData).

Authenticating to Microsoft Power BI XMLA

Azure AD

Azure AD is Microsoft’s multi-tenant, cloud-based directory and identity management service. It is user-based authentication that requires that you set AuthScheme to AzureAD.

OAuth

CData provides an embedded OAuth application that simplifies authentication. You can, however, create a custom application for authentication. For information about creating a custom application and reasons for doing so, see Creating a Custom OAuth App.

For authentication, the only difference between using the CData-provided (embedded) application and creating your own custom application is that you must set two additional connection properties in the Advanced Tab when using custom OAuth applications.

Before you connect, for Custom Azure AD applications only, set the following variables:

• OAuthClientId: The client Id assigned when you registered your custom OAuth application.
• OAuthClientSecret: The client secret assigned when you registered your custom OAuth application.

Click Connect to Microsoft Power BI XMLA to open the OAuth endpoint in your default browser. Log in and grant permissions to the application.

The driver then completes the OAuth process as follows:

• Extracts the access token from the callback URL.
• Obtains a new access token when the old one expires.
• Saves OAuth values so that they persist across connections.

Azure Service Principal

Azure Service Principal is role-based application-based authentication. This means that authentication is done per application, rather than per user. All tasks taken by the app are done without a default user context, but based on the assigned roles. The application access to the resources is controlled through the assigned roles' permissions.

To use Azure Service Principal authentication, you must:

• Set up the ability to assign a role to the authentication application. To do this, create a custom OAuth AD application, as described in Creating a Custom OAuth App.
• Register an application with an Azure AD tenant, to create a new service principal that can be used with the role-based access control, to access resources in your subscription.

Do the following:

1. Create a custom Azure AD application, as described in Creating a Custom OAuth App.
2. Assign a role to the application:
   1. Use the search bar to search for the Subscriptions service.
   2. Open the Subscriptions page.
   3. Select the subscription to which to assign the application.
   4. Open the Access control (IAM).
   5. Select Add > Add role assignment. Microsoft Power BI XMLA opens the Add role assignment page.
   6. Assign your custom Azure AD application the role of Owner.

Client Credentials

Client credentials refers to a flow in OAuth where there is no direct user authentication taking place. Instead, credentials are created for just the application itself. All tasks taken by the application are done without a default user context. This makes the authentication flow a bit different from the standard flow.

All permissions related to the client OAuth flow require admin consent. This means you cannot use the application embedded with the CData Sync App in the client OAuth flow. You must create your own OAuth application to use client credentials. See Creating a Custom OAuth App for more information.

In your App Registration in portal.azure.com, navigate to API Permissions and select the Microsoft Graph permissions. There are two distinct sets of permissions: Delegated permissions and Application permissions. The permissions used during client credential authentication are under "Application Permissions".

Select the permissions you require for your integration. After you do this, set the following connection properties:

• AuthScheme: AzureServicePrincipal.
• InitiateOAuth: GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
• AzureTenant: The tenant you wish to connect to.
• OAuthGrantType: CLIENT.
• OAuthClientId: The client Id in your application settings.
• OAuthClientSecret: The client secret in your application settings.

Authentication with client credentials takes place automatically like any other connection, except there is no window opened prompting the user. Because there is no user context, there is no need for a browser popup. Connections will take place and be handled internally.

Auth Certificate

Auth Certificate refers to an OAuth flow that uses a certificate to enable server-to-server authentication. All permissions related to the client OAuth flow require admin consent. This means you cannot use the application embedded with the CData Sync App in the client OAuth flow. You must create your own OAuth application to use an OAuth certificate. See Creating a Custom OAuth App for more information.

In your App Registration in portal.azure.com, navigate to API Permissions and select the client Graph permissions. There are two distinct sets of permissions: Delegated permissions and Application permissions. The permissions used during certificate authentication are under "Application Permissions".

Select the permissions that apply to your particular integration. After you do this, set the following connection properties:

• AuthScheme: AzureServicePrincipalCert.
• AzureTenant: The tenant to which you need to connect.
• OAuthJWTCert: The JWT Certificate store.
• OAuthJWTIssuer: The OAuth client Id.
• OAuthJWTCertType: The type of the certificate store specified by OAuthJWTCert.

Certificate authentication takes place automatically. Since there is no user context, there is no pop-up to signal the point at which authentication occurs. Connections are made and handled internally.

Creating a Custom OAuth Application

Microsoft Power BI XMLA supports authentication using Azure AD and Azure Service Principal, both of which are OAuth-based.

This topic describes how to:

• create and register custom OAuth application for Azure AD or Azure Service Principal
• create a custom OAuth application for use with client credentials

Azure AD

In portal.azure.com:

1. Log in to https://portal.azure.com.
2. In the left-hand navigation pane, select Azure Active Directory, then applicationRegistrations.
3. Click New registration.
4. Enter a name for the application.
5. Select the desired tenant setup: single- or multi-tenant, and public or private use.
   • If you select the default option, "Accounts in this organizational directory only", you must set the AzureTenant connection property to the Id of the Azure AD Tenant when establishing a connection with the CData Sync App. Otherwise, the authentication attempt fails with an error.
   • If your application is for private use only, specify Accounts in this organization directory only.
   • If you want to distribute your application, choose one of the multi-tenant options.

6. Set the redirect url to http://localhost:33333 (the Sync App's default) OR specify a different port and set CallbackURL to the exact reply URL you defined.
7. Click Register to register the new application. An application management screen displays.
   Note the value in Application (client) ID as the OAuthClientId and the Directory (tenant) ID as the AzureTenant.
8. Navigate to Certificates & Secrets and define the application authentication type. There are two types of authentication available: certificate (recommended) or client secret.
   • For certificate authentication: In Certificates & Secrets, select Upload certificate, then upload the certificate from your local machine.
   • For creating a new client secret: In Certificates & Secrets, select New Client Secret for the application and specify its duration. After the client secret is saved, Microsoft Power BI XMLA displays the key value. Copy this value, as it is displayed only once. This value becomes the OAuthClientSecret.

9. Select API Permissions > Add > Delegated permissions.
10. Select Power BI Service -> Delegated Permissions -> Dataset.Read.All and Workspace.Read.All.
11. Save your changes.
12. If you have specified the use of permissions that require admin consent (such as the Application Permissions), you can grant them from the current tenant on the API Permissions page.

Azure Service Principal

To use Azure Service Principal authentication, you must set up the ability to assign a role to the authentication application, then register an application with the Azure AD tenant to create a new Service Principal. That new Service Principal can then leverage the assigned role-based access control to access resources in your subscription.

In portal.azure.com:

1. Create a custom OAuth AD application, as described above.
2. Use the search bar to search for the Subscriptions service.
3. Open the Subscriptions page.
4. Select the subscription to which to assign the application.
5. Open the Access control (IAM).
6. Select Add > Add role assignment. Microsoft Power BI XMLA opens the Add role assignment page.
7. Assign your custom Azure AD application the role of Owner.

Consent for Client Credentials

OAuth supports the use of client credentials to authenticate. In a client credentials OAuth flow, credentials are created for the authenticating application itself. The auth flow acts just like the usual auth flow except that there is no prompt for an associated user to provide credentials. All tasks accepted by the application are executed outside of the context of a default user.

Note: Since the embedded OAuth credentials authenticate on a per-user basis, you cannot use them in a client OAuth flow. You must always create a custom OAuth application to use client credentials.

In portal.azure.com:

1. Create a custom OAuth application, as described above.
2. Navigate to App Registrations.
3. Find the application you just created, and open API Permissions.
4. Select the Microsoft Graph permissions. There are two distinct sets of permissions: Delegated and Application.
5. Under Application Permissions, select the permissions you require for your integration.

Client OAuth Flow With a Certificate

All permissions related to the client OAuth flow require admin consent. This means the application embedded with the CData Sync App cannot be used in the client OAuth flow. You must create your own OAuth application in order to use client credentials, as described above.

After your OAuth application is created:

1. Return to portal.azure.com.
2. Navigate to App Registration.
3. Find the application you just created.
4. Under API Permissions, select the Microsoft Graph permissions.
   There are two distinct sets of permissions: Delegated permissions and Application permissions. The permissions used during client credential authentication are under Application Permissions.
5. Select the permissions that apply to your particular integration.

Creating a Custom OAuth Application

Microsoft Power BI XMLA supports authentication using Azure AD and Azure Service Principal, both of which are OAuth-based.

This topic describes how to:

3. Click New registration.
4. Enter a name for the application.
5. Select the desired tenant setup: single- or multi-tenant, and public or private use.
   • If you select the default option, "Accounts in this organizational directory only", you must set the AzureTenant connection property to the Id of the Azure AD Tenant when establishing a connection with the CData Sync App. Otherwise, the authentication attempt fails with an error.
   • If your application is for private use only, specify Accounts in this organization directory only.
   • If you want to distribute your application, choose one of the multi-tenant options.

6. Set the redirect url to http://localhost:33333 (the Sync App's default) OR specify a different port and set CallbackURL to the exact reply URL you defined.
7. Click Register to register the new application. An application management screen displays.

11. Save your changes.
12. If you have specified the use of permissions that require admin consent (such as the Application Permissions), you can grant them from the current tenant on the API Permissions page.

Azure Service Principal

To use Azure Service Principal authentication, you must set up the ability to assign a role to the authentication application, then register an application with the Azure AD tenant to create a new Service Principal. That new Service Principal can then leverage the assigned role-based access control to access resources in your subscription.

In portal.azure.com:

1. Create a custom OAuth AD application, as described above.

Microsoft Power BI XMLA is an OLAP database that exposes data as cubes, which you query with MDX (multidimensional expressions). The Sync App models these cubes in relational views that you can query with SQL-92. The following mapping is for the layout of the model:

• Catalog - Displayed in the Sync App as a Catalog.
• Cube - Displayed in the Sync App as a Schema.
• Measure - Available in the Sync App under the special Measures view.
• Dimension - Each dimension is exposed as a view.
• Level - Each individual level of a hierarchy is exposed as a column on the appropriate dimension view.

Joining Measures and Dimensions

In order to retrieve measures per specific level value, issue a join between the Measure view and any Dimension or set of dimensions. For example, issuing the following will retrieve the number of customers in each city:

SELECT m.[Customer Count], c.[City] 
FROM [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Customer AS c 
INNER JOIN [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Measures AS m

Note that there is no ON condition necessary. That is because tables are already related appropriately in Microsoft Power BI XMLA. If you are using a tool that requires ON conditions, set IncludeJoinColumns to true. This will append a number of foreign key columns to each view which will relate them to one another another. These columns will not return data on their own, but may be picked up on automatically with tools to construct the ON conditions for joins where needed.

Aggregating Data

Data stored in Microsoft Power BI XMLA is already aggregated. In many cases, attempting to retrieve an aggregate may be syntactically equivalent to not specifying anything. For example, the following query will return the exact same data as the previous:

SELECT SUM(m.[Customer Count]), c.[City] 
FROM [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Customer AS c 
INNER JOIN [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Measures AS m
GROUP BY c.[City]

The exception to this rule is when an aggregation of filtered results is requested. In such cases, a calculation will be requested from Microsoft Power BI XMLA. For example, to calculate the sum and average of customers in France and Germany:

SELECT SUM(m.[Customer Count]), AVG(m.[Customer Count]), c.[Country] 
FROM [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Customer AS c 
INNER JOIN [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Measures AS m
WHERE c.[Country] IN ('France', 'Germany')
GROUP BY c.[Country]

Selecting Multiple Hierarchies

In Microsoft Power BI XMLA, individual dimensions are made up of hierarchies which may have one or more levels. For instance, the AdventureWorks Customers table has City, Country and Gender. City and Country are part of the same hierarchy while Gender is its own hierarchy.

When selecting multiple hierarchies, the method to support this is to cross join the values in MDX. While not obvious from a relational table model of the data as the Sync App presents, this can cause for very expensive queries to be executed. For example, executing the following:

SELECT c.[Country], m.[Customer Count]
FROM [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Customer AS c 
INNER JOIN [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Measures AS m

Will result in 6 rows. However, selecting Gender as well:

SELECT c.[Country], c.[Gender], m.[Customer Count]
FROM [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Customer AS c 
INNER JOIN [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Measures AS m

Will now result in 12 rows. It is because Gender and Country are on different hierarchies, thus a crossjoin is required in order to return both together. Each additional hierarchy added to the SELECT will multiply the total results by the number of available values in that hierarchy. Thus to get a count of how many rows to expect, one can execute the following:

SELECT (COUNT(c.[Country])*COUNT(c.[Gender])) AS totalrows
FROM [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Customer AS c 

Response Row Limit

Due to how selecting multiple hierarchies will multiply the total number of result rows, it is possible to balloon the number of response rows very quickly, which will result in timeouts. In order to try and give some visibility into what queries will be very expensive, the ResponseRowLimit connection property has been added as a mechanism to guide users into an ideal configuration. When set, it will calculate how many rows to expect before any query is executed. If the number of predicted rows exceeds the limit, an error will be thrown indicating how many rows to expect back with the query.

It is recommended to select only the columns required or to apply a WHERE criteria. Both can significantly reduce the number of response rows, which will have a huge impact on performance. If you are already familiar with the Sync App and what queries may be expensive, ResponseRowLimit may be disabled by setting it to 0.

Fine Tuning Data Access

The following are properties that allow for more granular control over data access:

• UseMDX: Indicates if MDX queries are being submitted. By default this is false, which will cause the driver to accept only SQL-92 compliant queries.

  Setting this property to true will cause all queries to be passed through directly to Microsoft Power BI XMLA.

• ExtraProperties: Additional properties to submit along with an MDX query. Only meaningful if UseMDX is true.
• IncludeJoinColumns: Boolean indicating if extra columns used to make ON conditions with joins should be added.

  These do not come back with any values - they are added purely to enable tools that require them in order to automatically set up relationships between tables when creating joins.

• ResponseRowLimit: Sets a calculated limit on the number of rows to allow the user to select before returning an error.

  Because queries are being translated to MDX, selecting only a few columns may exponentially multiply the number of expected results.

  For this reason, ResponseRowLimit is available to try and give some guidance on what types of queries are likely to result in a Timeout. May be disabled by setting to 0.

This section details a selection of advanced features of the Microsoft Power BI XMLA Sync App.

User Defined Views

The Sync App allows you to define virtual tables, called user defined views, whose contents are decided by a pre-configured query. These views are useful when you cannot directly control queries being issued to the drivers. See User Defined Views for an overview of creating and configuring custom views.

SSL Configuration

Use SSL Configuration to adjust how Sync App handles TLS/SSL certificate negotiations. You can choose from various certificate formats; see the SSLServerCert property under "Connection String Options" for more information.

Firewall and Proxy

Configure the Sync App for compliance with Firewall and Proxy, including Windows proxies and HTTP proxies. You can also set up tunnel connections.

Query Processing

The Sync App offloads as much of the SELECT statement processing as possible to Microsoft Power BI XMLA and then processes the rest of the query in memory (client-side).

See Query Processing for more information.

Logging

See Logging for an overview of configuration settings that can be used to refine CData logging. For basic logging, you only need to set two connection properties, but there are numerous features that support more refined logging, where you can select subsets of information to be logged using the LogModules connection property.

Customizing the SSL Configuration

By default, the Sync App attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store.

To specify another certificate, see the SSLServerCert property for the available formats to do so.

Connecting Through a Firewall or Proxy

HTTP Proxies

To connect through the Windows system proxy, you do not need to set any additional connection properties. To connect to other proxies, set ProxyAutoDetect to false.

In addition, to authenticate to an HTTP proxy, set ProxyAuthScheme, ProxyUser, and ProxyPassword, in addition to ProxyServer and ProxyPort.

Other Proxies

Set the following properties:

• To use a proxy-based firewall, set FirewallType, FirewallServer, and FirewallPort.
• To tunnel the connection, set FirewallType to TUNNEL.
• To authenticate, specify FirewallUser and FirewallPassword.
• To authenticate to a SOCKS proxy, additionally set FirewallType to SOCKS5.

Overview

This section shows the available API objects and provides more information on executing SQL to Microsoft Power BI XMLA APIs.

The Sync App models dimensions as tables, cubes as schemas, and a combination of the Workspace and DataSet Catalog as the Catalog. The Sync App supports connecting to multiple workspaces at the same time by supplying a comma-separated list of workspaces in the Workspace property. The result is that each workspace shows up in the catalogs as WorkspaceName_CatalogName.

Key Features

• The Sync App models Microsoft Power BI XMLA entities like documents, folders, and groups as relational views, allowing you to write SQL to query Microsoft Power BI XMLA data.
• Stored procedures allow you to execute operations to Microsoft Power BI XMLA.
• Live connectivity to these objects means any changes to your Microsoft Power BI XMLA account are immediately reflected when using the Sync App.

Measure Attributes

By default, all measure attributes are listed in a 'Measures' view. However, you can set SplitMeasures to 'true' to split the measures view; the result is each measure attribute is included in its respective view based on the Measure Group value. Further classification based on 'Measure Directories' is not included.

Stored Procedures

Stored Procedures are function-like interfaces to Microsoft Power BI XMLA. Stored procedures allow you to execute operations to Microsoft Power BI XMLA, including downloading documents and moving envelopes.

The connection string properties are the various options that can be used to establish a connection. This section provides a complete list of the options you can configure in the connection string for this provider. Click the links for further details.

---

Property	Description
AzureTenant	The Microsoft Online tenant being used to access data. If not specified, your default tenant is used.
AzureEnvironment	The Azure Environment to use when establishing a connection.

The Microsoft Online tenant being used to access data. If not specified, your default tenant is used.

Remarks

The Microsoft Online tenant being used to access data. For instance, contoso.onmicrosoft.com. Alternatively, specify the tenant Id. This value is the directory Id in the Azure Portal > Azure Active Directory > Properties.

Typically it is not necessary to specify the Tenant. This can be automatically determined by Microsoft when using the OAuthGrantType set to CODE (default). However, it may fail in the case that the user belongs to multiple tenants. For instance, if an Admin of domain A invites a user of domain B to be a guest user. The user will now belong to both tenants. It is a good practice to specify the Tenant, although in general things should normally work without having to specify it.

The AzureTenant is required when setting OAuthGrantType to CLIENT. When using client credentials, there is no user context. The credentials are taken from the context of the app itself. While Microsoft still allows client credentials to be obtained without specifying which Tenant, it has a much lower probability of picking the specific tenant you want to work with. For this reason, we require AzureTenant to be explicitly stated for all client credentials connections to ensure you get credentials that are applicable for the domain you intend to connect to.

The Azure Environment to use when establishing a connection.

Remarks

In most cases, leaving the environment set to global will work. However, if your Azure Account has been added to a different environment, the AzureEnvironment may be used to specify which environment. The available values are GLOBAL, CHINA, USGOVT, USGOVTDOD.

This section provides a complete list of the OAuth properties you can configure in the connection string for this provider.

---

Property	Description
OAuthClientId	The client Id assigned when you register your application with an OAuth authorization server.
OAuthClientSecret	The client secret assigned when you register your application with an OAuth authorization server.

The client Id assigned when you register your application with an OAuth authorization server.

Remarks

As part of registering an OAuth application, you will receive the OAuthClientId value, sometimes also called a consumer key, and a client secret, the OAuthClientSecret.

The client secret assigned when you register your application with an OAuth authorization server.

Remarks

As part of registering an OAuth application, you will receive the OAuthClientId, also called a consumer key. You will also receive a client secret, also called a consumer secret. Set the client secret in the OAuthClientSecret property.

This section provides a complete list of the JWT OAuth properties you can configure in the connection string for this provider.

---

Property	Description
OAuthJWTCert	The JWT Certificate store.
OAuthJWTCertType	The type of key store containing the JWT Certificate.
OAuthJWTCertPassword	The password for the OAuth JWT certificate.
OAuthJWTCertSubject	The subject of the OAuth JWT certificate.

The JWT Certificate store.

Remarks

The name of the certificate store for the client certificate.

The OAuthJWTCertType field specifies the type of the certificate store specified by OAuthJWTCert. If the store is password protected, specify the password in OAuthJWTCertPassword.

OAuthJWTCert is used in conjunction with the OAuthJWTCertSubject field in order to specify client certificates. If OAuthJWTCert has a value, and OAuthJWTCertSubject is set, a search for a certificate is initiated. Please refer to the OAuthJWTCertSubject field for details.

Designations of certificate stores are platform-dependent.

The following are designations of the most common User and Machine certificate stores in Windows:

MY	A certificate store holding personal certificates with their associated private keys.
CA	Certifying authority certificates.
ROOT	Root certificates.
SPC	Software publisher certificates.

In Java, the certificate store normally is a file containing certificates and optional private keys.

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e. PKCS12 certificate store).

The type of key store containing the JWT Certificate.

Use '*' to signify to accept all certificates. Note that this is not recommended due to security concerns.

This section provides a complete list of the Firewall properties you can configure in the connection string for this provider.

---

Property	Description
FirewallType	The protocol used by a proxy-based firewall.
FirewallServer	The name or IP address of a proxy-based firewall.
FirewallPort	The TCP port for a proxy-based firewall.
FirewallUser	The user name to use to authenticate with a proxy-based firewall.
FirewallPassword	A password used to authenticate to a proxy-based firewall.

The protocol used by a proxy-based firewall.

Remarks

This property specifies the protocol that the Sync App will use to tunnel traffic through the FirewallServer proxy. Note that by default, the Sync App connects to the system proxy; to disable this behavior and connect to one of the following proxy types, set ProxyAutoDetect to false.

Type	Default Port	Description
TUNNEL	80	When this is set, the Sync App opens a connection to Microsoft Power BI XMLA and traffic flows back and forth through the proxy.
SOCKS4	1080	When this is set, the Sync App sends data through the SOCKS 4 proxy specified by FirewallServer and FirewallPort and passes the FirewallUser value to the proxy, which determines if the connection request should be granted.
SOCKS5	1080	When this is set, the Sync App sends data through the SOCKS 5 proxy specified by FirewallServer and FirewallPort. If your proxy requires authentication, set FirewallUser and FirewallPassword to credentials the proxy recognizes.

To connect to HTTP proxies, use ProxyServer and ProxyPort. To authenticate to HTTP proxies, use ProxyAuthScheme, ProxyUser, and ProxyPassword.

The name or IP address of a proxy-based firewall.

Remarks

This property specifies the IP address, DNS name, or host name of a proxy allowing traversal of a firewall. The protocol is specified by FirewallType: Use FirewallServer with this property to connect through SOCKS or do tunneling. Use ProxyServer to connect to an HTTP proxy.

Note that the Sync App uses the system proxy by default. To use a different proxy, set ProxyAutoDetect to false.

The TCP port for a proxy-based firewall.

Remarks

This specifies the TCP port for a proxy allowing traversal of a firewall. Use FirewallServer to specify the name or IP address. Specify the protocol with FirewallType.

The user name to use to authenticate with a proxy-based firewall.

Remarks

The FirewallUser and FirewallPassword properties are used to authenticate against the proxy specified in FirewallServer and FirewallPort, following the authentication method specified in FirewallType.

A password used to authenticate to a proxy-based firewall.

Remarks

This property is passed to the proxy specified by FirewallServer and FirewallPort, following the authentication method specified by FirewallType.

This section provides a complete list of the Proxy properties you can configure in the connection string for this provider.

---

Property	Description
ProxyAutoDetect	This indicates whether to use the system proxy settings or not.
ProxyServer	The hostname or IP address of a proxy to route HTTP traffic through.
ProxyPort	The TCP port the ProxyServer proxy is running on.
ProxyAuthScheme	The authentication type to use to authenticate to the ProxyServer proxy.
ProxyUser	A user name to be used to authenticate to the ProxyServer proxy.
ProxyPassword	A password to be used to authenticate to the ProxyServer proxy.
ProxySSLType	The SSL type to use when connecting to the ProxyServer proxy.
ProxyExceptions	A semicolon separated list of destination hostnames or IPs that are exempt from connecting through the ProxyServer .

This indicates whether to use the system proxy settings or not.

Remarks

This takes precedence over other proxy settings, so you'll need to set ProxyAutoDetect to FALSE in order use custom proxy settings.

To connect to an HTTP proxy, see ProxyServer. For other proxies, such as SOCKS or tunneling, see FirewallType.

The hostname or IP address of a proxy to route HTTP traffic through.

Remarks

The hostname or IP address of a proxy to route HTTP traffic through. The Sync App can use the HTTP, Windows (NTLM), or Kerberos authentication types to authenticate to an HTTP proxy.

If you need to connect through a SOCKS proxy or tunnel the connection, see FirewallType.

By default, the Sync App uses the system proxy. If you need to use another proxy, set ProxyAutoDetect to false.

The TCP port the ProxyServer proxy is running on.

Remarks

The port the HTTP proxy is running on that you want to redirect HTTP traffic through. Specify the HTTP proxy in ProxyServer. For other proxy types, see FirewallType.

The authentication type to use to authenticate to the ProxyServer proxy.

Remarks

This value specifies the authentication type to use to authenticate to the HTTP proxy specified by ProxyServer and ProxyPort.

Note that the Sync App will use the system proxy settings by default, without further configuration needed; if you want to connect to another proxy, you will need to set ProxyAutoDetect to false, in addition to ProxyServer and ProxyPort. To authenticate, set ProxyAuthScheme and set ProxyUser and ProxyPassword, if needed.

The authentication type can be one of the following:

• BASIC: The Sync App performs HTTP BASIC authentication.
• DIGEST: The Sync App performs HTTP DIGEST authentication.
• NEGOTIATE: The Sync App retrieves an NTLM or Kerberos token based on the applicable protocol for authentication.
• PROPRIETARY: The Sync App does not generate an NTLM or Kerberos token. You must supply this token in the Authorization header of the HTTP request.

If you need to use another authentication type, such as SOCKS 5 authentication, see FirewallType.

A user name to be used to authenticate to the ProxyServer proxy.

Remarks

The ProxyUser and ProxyPassword options are used to connect and authenticate against the HTTP proxy specified in ProxyServer.

You can select one of the available authentication types in ProxyAuthScheme. If you are using HTTP authentication, set this to the user name of a user recognized by the HTTP proxy. If you are using Windows or Kerberos authentication, set this property to a user name in one of the following formats:

user@domain
domain\user

A password to be used to authenticate to the ProxyServer proxy.

Remarks

This property is used to authenticate to an HTTP proxy server that supports NTLM (Windows), Kerberos, or HTTP authentication. To specify the HTTP proxy, you can set ProxyServer and ProxyPort. To specify the authentication type, set ProxyAuthScheme.

If you are using HTTP authentication, additionally set ProxyUser and ProxyPassword to HTTP proxy.

If you are using NTLM authentication, set ProxyUser and ProxyPassword to your Windows password. You may also need these to complete Kerberos authentication.

For SOCKS 5 authentication or tunneling, see FirewallType.

By default, the Sync App uses the system proxy. If you want to connect to another proxy, set ProxyAutoDetect to false.

The SSL type to use when connecting to the ProxyServer proxy.

Remarks

This property determines when to use SSL for the connection to an HTTP proxy specified by ProxyServer. This value can be AUTO, ALWAYS, NEVER, or TUNNEL. The applicable values are the following:

AUTO	Default setting. If the URL is an HTTPS URL, the Sync App will use the TUNNEL option. If the URL is an HTTP URL, the component will use the NEVER option.
ALWAYS	The connection is always SSL enabled.
NEVER	The connection is not SSL enabled.
TUNNEL	The connection is through a tunneling proxy. The proxy server opens a connection to the remote host and traffic flows back and forth through the proxy.

A semicolon separated list of destination hostnames or IPs that are exempt from connecting through the ProxyServer .

Remarks

The ProxyServer is used for all addresses, except for addresses defined in this property. Use semicolons to separate entries.

Note that the Sync App uses the system proxy settings by default, without further configuration needed; if you want to explicitly configure proxy exceptions for this connection, you need to set ProxyAutoDetect = false, and configure ProxyServer and ProxyPort. To authenticate, set ProxyAuthScheme and set ProxyUser and ProxyPassword, if needed.

This section provides a complete list of the Logging properties you can configure in the connection string for this provider.

---

Property	Description
LogModules	Core modules to be included in the log file.

Core modules to be included in the log file.

Remarks

Only the modules specified (separated by ';') will be included in the log file. By default all modules are included.

See the Logging page for an overview.

This section provides a complete list of the Schema properties you can configure in the connection string for this provider.

---

Property	Description
Location	A path to the directory that contains the schema files defining tables, views, and stored procedures.
BrowsableSchemas	This property restricts the schemas reported to a subset of the available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC.
Tables	This property restricts the tables reported to a subset of the available tables. For example, Tables=TableA,TableB,TableC.
Views	Restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC.
Catalog	The Power BI workspace and dataset to use.
IncludeJoinColumns	Set this to true to include extra join columns on each table.

A path to the directory that contains the schema files defining tables, views, and stored procedures.

Remarks

The path to a directory which contains the schema files for the Sync App (.rsd files for tables and views, .rsb files for stored procedures). The folder location can be a relative path from the location of the executable. The Location property is only needed if you want to customize definitions (for example, change a column name, ignore a column, and so on) or extend the data model with new tables, views, or stored procedures.

If left unspecified, the default location is "%APPDATA%\\CData\\PowerBIXMLA Data Provider\\Schema" with %APPDATA% being set to the user's configuration directory:

Platform	%APPDATA%
Windows	The value of the APPDATA environment variable
Linux	~/.config

This property restricts the schemas reported to a subset of the available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC.

Remarks

Listing the schemas from databases can be expensive. Providing a list of schemas in the connection string improves the performance.

This property restricts the tables reported to a subset of the available tables. For example, Tables=TableA,TableB,TableC.

Remarks

Listing the tables from some databases can be expensive. Providing a list of tables in the connection string improves the performance of the Sync App.

This property can also be used as an alternative to automatically listing views if you already know which ones you want to work with and there would otherwise be too many to work with.

Specify the tables you want in a comma-separated list. Each table should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Tables=TableA,[TableB/WithSlash],WithCatalog.WithSchema.`TableC With Space`.

Note that when connecting to a data source with multiple schemas or catalogs, you will need to provide the fully qualified name of the table in this property, as in the last example here, to avoid ambiguity between tables that exist in multiple catalogs or schemas.

Restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC.

Remarks

Listing the views from some databases can be expensive. Providing a list of views in the connection string improves the performance of the Sync App.

This property can also be used as an alternative to automatically listing views if you already know which ones you want to work with and there would otherwise be too many to work with.

Specify the views you want in a comma-separated list. Each view should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Views=ViewA,[ViewB/WithSlash],WithCatalog.WithSchema.`ViewC With Space`.

Note that when connecting to a data source with multiple schemas or catalogs, you will need to provide the fully qualified name of the table in this property, as in the last example here, to avoid ambiguity between tables that exist in multiple catalogs or schemas.

The Power BI workspace and dataset to use.

Remarks

The Sync App combines each Power BI workspace and dataset into a single catalog name. For example, if you have a workspace called MyWorkspace and a dataset called MyDataset then its catalog name will be MyWorkspace_MyDataset.

By default the Sync App will report all workspaces and datasets as separate catalogs. A query can either use the catalog directly, or leave off the catalog to have the Sync App search for a matching table.

-- Use this specific catalog
SELECT ... FROM MyWorkspace_MyDataset.Model.MyDimension

-- Search for a catalog containing this table
SELECT ... FROM Model.MyDimension

However, if you have enabled UseMDX then you may want to set this value so that MDX queries go to the correct workspace and dataset. The Sync App cannot determine the workspace and dataset automatically from an MDX query.

Set this to true to include extra join columns on each table.

Remarks

Some tools may require an ON condition (or generate them automatically) based on foreign key references. By setting IncludeJoinColumns to true, every table will include a foreign key reference to the other tables. These columns will not return any data and are not useful for anything other than passing as ON conditions to perform joins upon.

In Microsoft Power BI XMLA, the dimensions and measures making up the tables are already related naturally. There is no context on which to join them provided. Therefore, the CData Sync App supports joining without specifying an ON condition, so they are optional to specify.

This section provides a complete list of the Miscellaneous properties you can configure in the connection string for this provider.

---

Property	Description
CustomHeaders	Other headers as determined by the user (optional).
ExposeMemberKeys	Determines if each level should be converted into a measure, allowing calculations to be performed on the measure.
ExpressionInDescription	Set this to true to report expressions as part of the description on measure columns.
ExtraProperties	Additional properties to submit on each MDX request to Microsoft Power BI XMLA.
MaxRows	Limits the number of rows returned when no aggregation or GROUP BY is used in the query. This takes precedence over LIMIT clauses.
Other	These hidden properties are used only in specific use cases.
ResponseRowLimit	The number of response rows to allow before triggering an error. Set to 0 for no limit.
ShowHiddenEntities	Set this to true to include hidden dimensions, measures and levels.
SplitMeasures	Set this to true to split Measures table into individual tables.
SplitMeasuresOn	Use this property in conjunction with SplitMeasures to set the priority for how measures should be organized into tables.
Timeout	The value in seconds until the timeout error is thrown, canceling the operation.
UseMDX	Set this to true to pass MDX queries to Microsoft Power BI XMLA as-is.
UserDefinedViews	A filepath pointing to the JSON configuration file containing your custom views.
Workspace	The comma separated PowerBI workspace(s) to connect to.

Other headers as determined by the user (optional).

Remarks

This property can be set to a string of headers to be appended to the HTTP request headers created from other properties, like ContentType, From, and so on.

The headers must be of the format "header: value" as described in the HTTP specifications. Header lines should be separated by the carriage return and line feed (CRLF) characters.

Use this property with caution. If this property contains invalid headers, HTTP requests may fail.

This property is useful for fine-tuning the functionality of the Sync App to integrate with specialized or nonstandard APIs.

Determines if each level should be converted into a measure, allowing calculations to be performed on the measure.

Remarks

By default, all levels are of type String. Enabling this option allows a level to be resolved down to its key property, creating a measure that has the level's DBType data type. Calculations can then be performed on the measure.

Set this to true to report expressions as part of the description on measure columns.

Remarks

The Sync App reports the remarks for several types of entities (dimensions, measures, measure groups and heirarchies) as table and column descriptions. By default, the Sync App will include only the remarks in measure column descriptions.

If this option is enabled, then the measure expression is included in the measure column description, along with the remarks. The descriptions on other types of entities are not affected.

Additional properties to submit on each MDX request to Microsoft Power BI XMLA.

Remarks

When setting UseMDX to true, properties may be specified using this connection property to fill out extra values in the PropertiesList of the XMLA request. Use name=value pairs separated by a semicolon to submit the properties. For example, Catalog=MyCatalog;Cube=MyCube;.

A list of properties may be found by executing SELECT * FROM $System.DISCOVER_PROPERTIES.

Limits the number of rows returned when no aggregation or GROUP BY is used in the query. This takes precedence over LIMIT clauses.

Remarks

Limits the number of rows returned when no aggregation or GROUP BY is used in the query. This takes precedence over LIMIT clauses.

These hidden properties are used only in specific use cases.

Remarks

The properties listed below are available for specific use cases. Normal driver use cases and functionality should not require these properties.

Specify multiple properties in a semicolon-separated list.

Integration and Formatting

DefaultColumnSize	Sets the default length of string fields when the data source does not provide column length in the metadata. The default value is 2000.
ConvertDateTimeToGMT	Determines whether to convert date-time values to GMT, instead of the local time of the machine.
RecordToFile=filename	Records the underlying socket data transfer to the specified file.

The number of response rows to allow before triggering an error. Set to 0 for no limit.

Remarks

Selecting a lot of columns results in a number of crossjoins occurring under the hood when translated to something that is acceptable for Microsoft Power BI XMLA. This is not intuitive if you are not familiar with MDX. It can easily result in very large responses that time out. The ResponseRowLimit is designed to alert the user to very expensive requests.

Set this to true to include hidden dimensions, measures and levels.

Remarks

By default the Sync App does not report entities that Microsoft Power BI XMLA marks as hidden. Enabling this option allows you to query them.

Set this to true to split Measures table into individual tables.

Remarks

All measures are currently grouped into a single table 'Measures'. Set this to true to split Measures table into individual tables (if a table only contains measures) and include measures into respective dimensions tables.

Use this property in conjunction with SplitMeasures to set the priority for how measures should be organized into tables.

Remarks

This property controls the order in which measure storage attributes are used to sort them into subtables when SplitMeasures is true. Provide a comma-delimited list of storage methods in the order they should be prioritized. Available values are:

• MeasureGroup
• DisplayFolder

Split-Measure tables will be named according to whichever attribute comes first in the list, or sorted into a generic 'Measures' table if none of the values in the list are populated for the measure.

The value in seconds until the timeout error is thrown, canceling the operation.

Remarks

If Timeout = 0, operations do not time out. The operations run until they complete successfully or until they encounter an error condition.

If Timeout expires and the operation is not yet complete, the Sync App throws an exception.

Set this to true to pass MDX queries to Microsoft Power BI XMLA as-is.

Remarks

You can execute SQL-92 SELECT queries to the views modeled by the Sync App; set this property to instead execute MDX queries directly to Microsoft Power BI XMLA.

A filepath pointing to the JSON configuration file containing your custom views.

Remarks

User Defined Views are defined in a JSON-formatted configuration file called UserDefinedViews.json. The Sync App automatically detects the views specified in this file.

You can also have multiple view definitions and control them using the UserDefinedViews connection property. When you use this property, only the specified views are seen by the Sync App.

This User Defined View configuration file is formatted as follows:

• Each root element defines the name of a view.
• Each root element contains a child element, called query, which contains the custom SQL query for the view.

For example:

{
	"MyView": {
		"query": "SELECT * FROM [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Customer WHERE MyColumn = 'value'"
	},
	"MyView2": {
		"query": "SELECT * FROM MyTable WHERE Id IN (1,2,3)"
	}
}

Use the UserDefinedViews connection property to specify the location of your JSON configuration file. For example:

"UserDefinedViews", C:\Users\yourusername\Desktop\tmp\UserDefinedViews.json

Note that the specified path is not embedded in quotation marks.

The comma separated PowerBI workspace(s) to connect to.

Remarks

The comma separated PowerBI workspace(s) to connect to. If not specified, objects from all workspaces will be available. This will cause extra requests to be executed to list objects from all workspaces.

Note: The workspace names are case-sensitive.
