I have customers that I have given a reviewer license to. They want to be able to see the details behind the summary hours and expenses I can make available on a project or task report. Unfortunately, if I create the report - natively Reviewer user levels cannot see the data. So I need to setup the report to Run As another user with higher level access (e.g. me). This creates a problem b/c they can then run the report as me and I have full access to the data - so they can conceivably see others folks data if they run it outside of the dashboard that I present to them.
