Thanks Suman for your prompt response.
But, I've already followed above steps after which a user with Advanced Reporting - Navigate right can see and run the reports.
Once the user runs a report by right clicking on it & selecting run, the report gets generated in the same IE tab. Now, when user again wants to go back to the repository by clicking on view repository, repository shows blank with no reports.
This issue exists till user don't clear the IE cache. But, after generating a report once again this issue comes.
Request you to check this behavior at you end & let me know if you have any solution for the same.
