Sum() getting more result then the actual result in Grand total

Hi Techies,

Greetings!!

In the below screenshot, you can see values for the objects and finally it is having total in the end. Here, when i am working with WEBI, the grand total is giving incorrect total (more) as compared to actual total.

Everything is fine and checked already in the Universe level.

What could be the possible reason and could any one assist/guide me in resolving the issue.

BO 3.1 (SP 6),

Thank You!
