RLS in Sep 2025
- 8 months ago
Hi Vanchy_Liao ,
Based on your testing, your understanding is correct. This issue appears to be caused by a version mismatch: reports created using Power BI Desktop (RS) 2024-09 and then uploaded to PBIRS 2025-09 can trigger an infinite refresh when a user is not assigned to any RLS role. Since the same behavior can be reproduced with a simple empty report, this strongly indicates a PBIRS regression, not a report design problem.
At the moment, the practical workaround is to open the existing reports in Power BI Desktop (RS) 2025-09 and republish them to the latest PBIRS. This aligns the report metadata with the server version and avoids the refresh loop.
This should not be necessary long-term, so raising a Microsoft support case is still recommended when possible, as this likely requires a product fix.

Discovering an infinite refresh bug in your production PBIRS environment is alarming, especially with 100+ reports at stake. The fact that unassigned users trigger this in the 202409 version creates both immediate user experience issues and long-term maintenance worries.
First, don't manually rebuild all reports - that's unnecessary work until we confirm the scope. Start by testing if this affects only newly created reports or all existing ones. Pick 3-4 older reports and see if unassigned users encounter the same issue. If it's limited to new reports, you've avoided a massive rework.
For immediate relief, consider adding all active users to a basic "Viewer" role in your RLS configuration, even with minimal access. This should prevent the infinite refresh loop while you investigate. Also check Microsoft's community forums - others may have reported this 202409 bug and found workarounds.
Finally, this warrants opening a support case with Microsoft, as it appears to be a version-specific regression. Document your reproduction steps clearly: empty report + RLS roles + unassigned user = infinite refresh. While waiting for a fix, you might consider whether temporarily reverting to your previous PBIRS version is feasible, as this bug could impact user adoption and trust in your reporting system.

Hi Vanchy_Liao ,
Thanks for reaching out to the Microsoft fabric community forum.
Thanks for the clarification. Since the issue appears specifically when a report built in the 2024-09 Desktop for RS is uploaded into the 2025-09 PBIRS, it does point more strongly to a version-specific regression rather than a problem with your report design.
You’ve already done the right thing by confirming it’s reproducible with a simple empty report + RLS. This helps show that the behaviour didn’t exist in earlier PBIRS versions and likely started after the upgrade.
At this point, the best next step is to open a Microsoft support ticket with your exact reproduction steps, because this looks like something that needs engineering review.
