Right now we are on 15.2 in our PROD environment. People are asking for access to reporting. I see in later versions you have the option to give them access to reporting through the Classic UI with the Report - Access and other Report permissions by going to the Administration menu and giving access rights, however I don't see the Report - Access option in 15.2. Is there a way to get the reporting access to others without having to give them the advanced reporting access?
In 15.2 it is not possible to run Jaspersoft reports without going via Advanced Reporting.
However starting version 15.3, we added this option:
CA PPM 15.3 Change Impact and Upgrade - CA PPM - 15.3 - CA Technologies Documentation
SectionRun or Schedule Jaspersoft Reports Directly Inside Classic PPM
I would say I would recommend upgrading so you can benefit from that feature.
