Power BI Embedded

Hi p_da 
Thank you for reaching out to the Microsoft fabric community forum and kudos to johnbasha33 for their helpful input.

I understand you're using Power BI Embedded (App-Owns-Data) and want User A, with only Build permission on a dataset in Workspace A, to create a report and save it to their Personal Workspace using Save As, without needing Contributor role in Workspace A due to security concerns (e.g., RLS bypass). The authorization error occurs because Power BI requires write permissions (like Contributor) in Workspace A for cross-workspace saves, unless specific configurations are applied.

Use a Certified/Promoted Dataset with Tenant Settings this allows User A to save reports to their Personal Workspace with only Build permission.

• In Workspace A, go to the dataset, click the three-dot menu, select “Settings,” and mark it as Promoted (if you have permissions) or request Certification from your admin.
  
  
• Ask your tenant admin to enable “Allow users to connect to and build on datasets across workspaces” in the Power BI Admin Portal (Tenant settings > Export and sharing settings > Use datasets across workspaces) and Confirm User A has Build permission on the dataset in Workspace A (via “Manage Permissions”).
  
  
• User A creates a report in the embedded solution and uses Save As to save it to their Personal Workspace. This should now work without errors.
