Looking for conflicts in system access.

Not sure if I'm in the right forum but here goes:

Is there a report or such that will yield user name, active responsibilities - and capabilities of those responsibilities? For example:

Name                   Responsibilty                 Capabilities

John Smith          Buyer                              Create a PO, Create a Requisition, Autocreate a PO, Master a Supplier, Master an Item

                            Material Handler             Receive a PO, Transact a Receipt, Interorg Transfer, Enter Cycle Count  

In this case we do have a conflict as John can both create and receive a PO.

I know there are some canned reports concerning users and assigned responsibilities - but is there something out there that lists the end forms the responsibility can navigate to?
