This section describes how to edit the DSN configuration and then authenticate and connect to SAP HANA XSA 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.

If you're using Power BI's On-Premises Data Gateway with Standard mode, you must use the system DSN.

You must also specify a valid location for OAuthSettingsLocation (a path where OAuth credentials are locally stored to avoid repeated OAuth prompts).

This is because the Standard mode runs on service mode and can only access permitted locations, such as C:\Windows\ServiceProfiles\PBIEgwService\AppData\Local\Microsoft\On-premises data gateway.

SAP HANA XSA uses the OAuth authentication standard. Before connecting, it is necessary to establish an SAP HANA XSA OData Service. See Creating a Custom OAuth App for a guide.

To connect to SAP Hana XSA using password-based OAuth:

• OAuthClientId: Set this to the Client Id specified in the UAA service JSON file.
• OAuthClientSecret: Set this to the Client Secret specified in the UAA service JSON file.
• URL: Set this to the OData service endpoint.
• XSUAAURL: Set this to the UAA service url.
• User: Set your accounts username.
• Password: Set your accounts password

Once you've configured the OData Service, you can establish a connection using Custom Credentials.
