Universe does not exist or your security profile does not allow you to access it (WIS 00000))

Hello everyone,  I am facing this issue with a webi report.   Every time I try to access a report, I get this following error:

BI4.0 SP10

SUSE Linux.

Report type: Webi

The Universe does exist in the Enterprise Platform.    I have also made changes to the security profile in Universe to less restrictive.

and granted full access rights to the folder where the report is concerned and explicit grant Data Access for Universe IDT (in CMC) for the user.

Please suggest if I missed anything else .

Thank you, Rahul
