PO Approval for different PGrps other than his own.

Hi,

*f a user in SAP has both PO approver & creation rights then how to restrict him to approve Orders other than his purchasing group?"

I spite of limiting authorization to his only Pgrp,he is able to release the orders for other PGrps.

Please suggest which is that role or authorization object which would help in restricting the same.

Regards,

Puja.
