Hello All,

Hope you are doing well 🙂

I need your help in sorting out the issue iam facing in Power BI . I have around 8-10 tables in Power BI on which i have to do unpivot column transformation on 4 tables . when i do the unpivot transformation , my relationships get changed to Many to Many for visuals to show properly .

it was working for sometime when iam doing these transformations but all of sudden file getting corrupted with the error as shown in below snapshot . same happened even after trying with two files.

Hi @Anonymous ,

Please open power query editor and check the preview (refresh preview) of each table and see which one is giving this error. And select File > Options and Settings > Data Source Settings to clear your data source credentials.

If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.
Best Regards,
Winniz
