PowerBI Service - Download report is greyed out

PowerBI desktop is updated at the last version (and in general is happening also to report already in the Service) and there is no Incremental Refresh or Large dataset

Hi sunshine_1234 ,
Thanks for the question,

In addition to verifying Download Reports is enabled under Export and sharing settings in the Tenant settings.

Make sure that Use semantic models across workspaces is enabled for the entire organization under Workspace settings in the Admin portal.

Also there are certain limitations when downloading reports or datasets from Power BI Service:

1. Downloading a .pbix file is not supported as part of the deployment pipeline (ALM).

2. You can't download a copy of a report if the copy is saved in a workspace other than where the original report is saved.
3. Reports created using the Create button in Power BI Service, based on a semantic model in another workspace, cannot be downloaded.
4. Reports connected to Direct Lake semantic models are not eligible for download.

Here is the Microsoft link for detailed limitations for exporting data from Power Bi service.

Tip: If download restrictions persist, consider republishing the report directly to the desired workspace from Power BI Desktop or reviewing dataset permissions and workspace-level security settings.

Hope these help. Feel free to reach out for any assisatnce
