Blank Query Connection
Before using the Blank Query Connection and creating an access token, ensure your ServiceNow [admin] sets up and tests the configuration on the corresponding instances. Without this configuration, you won’t be able to create the access token.
By default, the OData feed is used for connecting to Microsoft Power BI. However, to meet a wider variety of user needs, the Blank Query Connection method has also been added.
This feature is especially helpful for companies using Single Sign On (SSO), as this login method often operates without the need for a password. The Blank Query Connection enables authorization without requiring a local ServiceNow password.
There are also a few features that are not available when using the Blank Query Connection:
The templates can’t be used with the Blank Query connection. They are built on OData, and the Blank Query can’t replace the OData connection.
There might be potential limitations for the scheduled refresh. Connection configuration issues are present when publishing the dashboard and scheduling a refresh.
To use the Blank Query Connection method, it’s required to generate an access token. Therefore, before exporting data, ensure that you have created a token.
