Need help to build Auditing Report of Users Rights on Universes

Dears,

I would like to ask if the following case can be applied in Business Objects!!

We want to build a report that allows you to get all the User names + Universe names which they have the authority to access them (Data Access)

Note that I've tried using the pre-built universe (ACTIVITY) but didnt get what i want...

I will be glad if you can suggest something to do regarding this issue..

your response is highly appreciated

P.S:

we are using BOXIR3 with SP3
