This section describes how to edit the DSN configuration and then authenticate and connect to Sage 300 APIs.

DSN Configuration

You can use the Microsoft ODBC Data Source Administrator to edit the DSN configuration. Note that the installation process creates a both a user DSN and a system DSN, as described in Installing the Connector.

Note: The connector stores connection information in the Windows registry. To ensure that the connector can write to the registry, either run Power BI as an administrator or use a User DSN for your connection instead of a System DSN.

User DSN

Complete the following steps to edit the DSN configuration:

1. Select Start > Search, and enter ODBC Data Sources in the Search box.
2. Choose the version of the ODBC Administrator that corresponds to the bitness of your Power BI Desktop installation (32-bit or 64-bit).
3. Select the system data source and click Configure.
4. Edit the information on the Connection tab and click OK.

System DSN

Configure the system DSN the same way as the user DSN, except you will need to switch to the System DSN tab before performing Step 3.

Before Authenticating

Sage 300 requires some initial setup in order to communicate over the Sage 300 Web API. The logged in user must have API access to one or all modules of the Sage300 instance. In Sage300 a user is assigned a security group. A security group is a set of permissions for each module. It is recommended that you use a different user other than the ADMIN user to access the API. The ADMIN user has a couple of extra steps in order to gain access to the API. Follow the steps below in order to obtain access to the API.

Creating a User

Skip this step if you have already created a new user or you would like to use an existing account.

• Open the Sage300 Desktop Application which is included in the installation of Sage300. Log in with the ADMIN account.
• Go to Administrative Services -> Users
• Fill in the required information and click Add

Setting up the Security Group

• Open the Sage300 Desktop Application which is included in the installation of Sage300. Log in with the ADMIN account.
• Go to Administrative Services -> Security Groups
• In the Application you will find all the modules of Sage300. The Group ID represents the security group you want to modify. Below you will find a list of permissions that you can check.
• (Optional)Create a new Security Group fill the Group ID, Group Description and check any of the permissions including the Sage 300 Web API permission. Lastly click Add(per each application required)
• Or select an existing Security Group you are going to assign to the User under Group ID and check the Sage 300 Web API permission in the end of permissions(per each application required).

Assigning a Security Group

• Open the Sage300 Desktop Application which is included in the installation of Sage300. Log in with the ADMIN account.
• Go to Administrative Services -> User Authorization
• Under User ID select your new/existing User
• Now for each Application assign the Group ID which you created/modified
• Once the user access is done, ensure that they have access to the web API. Replace 'server' with your Sage300 instance URL.

Connecting to Sage 300

The CData Power BI Connector for Sage 300 communicates to Sage 300 over the OData API. You can authenticate to Sage 300 using Basic authentication.

Basic Authentication

You must provide values for the following properties to successfully authenticate to Sage 300. Note that the provider will reuse the session opened by Sage 300 using cookies.

This means that your credentials will be used only on the first request to open the session. After that, cookies returned from Sage 300 will be used for authentication.

• Url: Set this to the url of the server hosting Sage 300. Construct a URL for the Sage 300 Web API as follows: {protocol}://{host-application-path}/v{version}/{tenant}/ For example, http://localhost/Sage300WebApi/v1.0/-/.
• User: Set this to the username of your account.
• Password: Set this to the password of your account.
