Datamart refresh fails

Hi, Melikag 

I am glad to help you.  

According to your description, you want to know why Datamart refresh fails? 

If I understand you correctly, then you can refer to my solution. 

Check Data Stream Output: Ensure that the data stream produces the expected output and that all necessary fields are populated correctly. 

Verify Data Mapping: Double-check the mapping between data streams and data charts. Ensure that all required fields (especially primaryDatamartObjectId) are correctly mapped and not missing. 

Update Power BI Service: Sometimes, it is possible to update to the latest version of Power BI Service to resolve such issues. So, make sure that you have the latest version of Power BI Service. 

Review Logs: Review the detailed logs for additional clues that may be causing the problem. Activity IDs and associated IDs are useful for this. 

If the issue persists, you can try to reconfigure the dataflow for refresh testing.

 I hope my suggestions give you good ideas, if you have any more questions, please clarify in a follow-up reply.

Best Regards,
Fen Ling,
