Hi All,

The query is using structure and hierarchy . we are not getting the error for all BW Quries .

Hi @ajithkrcapgemin ,

Please start Power BI desktop as administrator, then click on File -> Open to see if the same issue occurs. ensure the pbix file is saved in local drive.

Also，please remove all null columns.

Then custom column could be added and relationship with other columns has been restored.

Best regards.
