Hi Arun,
Checked the table per your suggestion but couldnt get any relevant information from there could you be more specific what should i check.
In the load monitor of those DTP i could see those requests having data but for the same requests i could not verify in the cube as those request are compressed.
Since the history data is huge so testing is taking time would appreciate if you suggest some quick work around to identify whether 0 records is not affecting the overall aggregation in cube.
Please let me know if you need additional information.
Thanks,
Abhishek
