Dataflows (legacy) and licensing

Hi Anonymous - Since you mentioned Workspace B and C are set up in Pro, make sure Workspace B (Prod_ws) and Workspace C (Thin reports) are fully compatible with the licensing level. For Pro users to access content, the workspaces should not contain Premium-only features.

Ensure that Pro users have been given proper access permissions to view the app. In Power BI, even if users have Pro licenses, they must be granted access to the app specifically.Go to the app permissions and ensure that the Pro users are added explicitly under "Permissions" or "Audience" for the app.

Since Workspace C uses DirectQuery from Workspace B, the users accessing Workspace C need appropriate access to the underlying dataset in Workspace B.

Ensure that Pro users have access to both Workspace B (the semantic model) and Workspace C (Thin reports). If they don’t have access to the data source in Workspace B, they will not be able to see the data in the app hosted in Workspace C.

Note: If the data size, refresh rates, or other workspace features exceed what is available for Pro users, consider upgrading the relevant workspaces to Premium per user capacity or Premium capacity.

Hope this information helps.
