Hi Rajesh,
Depending upon which version of XI3.1 you upgraded from, I would suggest, going to:
C:\Program Files (x86)\Business Objects\BusinessObjects Enterprise 12.0\Samples\universe
- select the folder that correlates to your auditing database type.
- import the universe to XI3.1
- test the universe in Webi to see if it returns duplicates.
As I was mentioning, it could be related to the version of the universe you're using.
Regards,
Wallie
