"Simple" Rolenames would be more than useful.
In production-environment we now have 3 BW-Roles - one for dev-BW, test-BW and prod-BW.
E.g.
BO Role - Cost Accounting
|-->BDA-Costaccounting
|-->BQA-Costaccounting
|-->BPA-Costaccounting
Due to transporting BO Roles from BO DEV -> BO QUA -> BO PROD
In every system we have to manually assign the BW-Role to BO-Role.
So if it is possible/working for users, it should work for roles as well. By now, it seems like "works as designed".
