With the introduction of Reports within CA PPM (15.3 and above) users may receive Error ' RPT-0022: You do not have proper privileges to run the report' when trying to run reports within CA PPM.
This may be caused by missing access rights in either CA PPM or on the Advanced Reporting folder.
Verify the user has access rights:
Advanced Reporting - Report Create
Advanced Reporting - Navigate
If the user has these rights already see if the report can be run from within Advanced Reporting.
If the report or folder cannot be seen in Advanced Reporting
Check the Role User rights on the folder and make sure the Role User has Read+Write access to the folder.
If you still receive the error please open a case.
