Assign Permissions to Cubes

[cognosqa]

I am using Cognos Powerplay web explorer. I want to be able to retain the "Save" & "Save As" buttons when I login using the administrator account, but I want to provide only the "Save As" option for all the other users. Currently with the "Save" button enabled, general users are overwriting the original cube view with their own personalized view. I want to be able to leave the original view intact, while still giving the users permission to use the "Save As" button to save their personalized view without overwriting the original cube. I am currently using Cognos 7.3.
