Exit for role determination via exit for scheduling agreement and contract?

Hi..

I have a requirement to fetch the agents in run-time for PO,PR,SCHEDULE AGREEMENT, CONTRACT..

For PO i am using EXIT : - M06E0005

For PR release i am using EXIT :- M06B0001

By using above 2 exits i am getting the agents at run-time...

Same way i need the EXIT for SCHEDULE AGREEMENT and CONTRACT..

if there is any EXIT for this please share with me..
