Assistance Needed with Power BI Datamart Refresh Issue

It seems like the Power BI Datamart refresh issue is likely caused by a data connection or schema problem. Here are some things to check:

1. Data Connections: Ensure all connections are properly configured and authenticated.
2. Data Transformations: Review any complex queries or transformations that might cause delays.
3. Query Dependencies: The error could be due to missing or incorrect data, so try refreshing individual tables.
4. Scheduled Refresh Settings: Verify that the refresh is within resource limits to avoid system overload.
5. Error Logs: Use the correlation ID for troubleshooting with Microsoft support.
6. Manual vs. Scheduled Refresh: Since manual refresh works, check for issues during initial load or network/resource availability during scheduled refreshes.

Hi KLeaner ,

Thanks for reaching out to the Microsoft fabric community forum. 

I would also take a moment to thank BhavinVyas3003 , for actively participating in the community forum and for the solutions you’ve been sharing in the community forum. Your contributions make a real difference. 

As a troubleshooting step, please review the data types and schema definitions in your tables to ensure there are no mismatches or issues that could be causing the refresh to fail.
Since the Datamart feature is currently in preview, some issues may still be expected. We recommend keeping an eye on updates and allowing some time, as improvements and fixes are actively being rolled out by Microsoft.
