hello @Chandra Prakash Matam ,

Thanks for the ask and using the forum .

The error shared is very generic and is not helping much . Did you atleast tried again and did you faced the same issue ? Is the data being loaded is huge ?

Thanks
Himanshu

Hi @HimanshuSinha-msft , thanks for replying
The error shared is very generic and is not helping much -- exactly, wish MS team throw better error message in next versions
Did you atleast tried again and did you faced the same issue ? - multiple times tried, this forum is last resort to find answer
Is the data being loaded is huge ? - of course, 76million

Hi @Chandra Prakash Matam ,

You can try following and see if this helps:

Connect to Analysis service from SQL Server Management Studio

Try processing the cube, here in the new window that opens it will tell you which all tables, partitions analysis service is able to process and help you narrow down the issue to specific table or partition

Once you narrow down see if there are duplicate records and may be you were expecting only one record etc in such situations also analysis service refresh fails and it gives generic error

I hope this helps.

Thanks,
Rahul
