Summary

Can you create a report of all the OTBI reports built and their permissions?

I'm an intermediate user of OTBI and have got to grips with building reports and dashboards. One thing I need is to be able to report on all the reports in our suite along with a list of the users/permissions for each one. Our IT department doesn't think it can be done but surely this is a standard auditing requirement?
