Role/Privilege needed to run a report/analysis?

Hi All, 

I've got a OBTI report/analysis question. Is it possible to see what role/privilege is needed to run a report/analysis? We have a benefits/payroll analysis report that through trial and error we have determined that a specific custom Payroll Data role would be needed to run this analysis report but I'm hoping to determine what privilege or data access itself is needed without having to assign that specific data role. Any suggestions would be appreciated.

Thank you,
