You may have a need to provide a user the ability to run all "out of box" reports in Advanced Reporting / Jaspersoft. However, you do not want to provide them the "Advanced Reporting - Administrator" in PPM.
One way to accomplish that would be to assign the user the Jaspersoft role: "CSK_ALL_REPORTS_DOMAINS".
In Advanced Reporting, navigate to "Manage" > "Users". Edit the user you would want to have this access and assign the role as shown below in Figure 1
For more information on the "CSK_*" roles and what they provide, please refer to Chapter 8 in the PMO Advanced Reporting Guide:
