Schedule refresh for Dashboard hosted on Workspace in a different tenant - Oauth not supported

Hi RandomDept,

Thanks for reaching out to the Microsoft fabric community forum.

Based on the error message "The OAuth authentication method isn't supported for this data source", It looks like  that the semantic model is connecting to a data source in a different tenant, which introduces authentication limitations. There may be various reasons for that like some data sources do not support OAuth2 authentication for refresh across tenants or there may be some conditional access policies in the source tenant that may be blocking OAuth2 authentication. You can also check if the data source requires authentication through Service Principal rather than OAuth2 as certain enterprise data sources authenticate using Service Principal.

You can check the Supported Authentication Methods for your data sources and you can also cross check if the Power BI tenant has the necessary permissions to access the data source.

I would also take a moment to thank lbendlin, for actively participating in the community forum and for the solutions you’ve been sharing in the community forum. Your contributions make a real difference.

If I misunderstand your needs or you still have problems on it, please feel free to let us know.  

Best Regards,
Hammad.
