How to display users with their assigned list of reports or how to see reports assigned to roles.

I would like to find

1) list of reports assigned to user. and

2) list of reports assigned to roles.

from the modules or info area I have SCM(40 reports), HCM(60) and CRM(100). We have total 200 reports. I would like to find the result through within SAP BW . (T-code or table.)

I can find user information from SUIM  to find list of users, roles and profiles etc. But is their any way I can a find list of reports .

However I could search the list of query through se16-> rsrrepdir (table name), I got 10,000 queries. But I don't know which query belong to which infoarea and I only need reports which belong to SCM, HCM and CRM so that I can export to excel spreading.

Please advice.
