Hi Karthik,
I am trying your recommendation, but cant find the "Change preferences" under General rights.
The "Change preferences" from General that you are talking about is already in the Access level that I assigned to the user/user group. So that is not the issue.
I specifically tested and found that, if I give WEBI application access to end user in the Launchpad, the 'Preferences" link shows the Web Intelligence options in the launchpad where I can set the View mode and other settings.
When I mean users should not be given WEBI access, I am talking about access to the WEBI application from the Launchpad, My Appplications Area.
In our organization we do not want to give end user access to WEBI application as we dont want them to build adhoc reports.
This option is available only for Power users/Admins.
Thank you
Suman
