[PO] Contract Purchase Agreement (CPA) - Controls at Amount Agreed

Would I-Procurement (IPROC) validates if the release amount is more than the "Amount Agreed" in a CPA?

IPROC still allows PR and PO to be created, and there is no validation, till the PO get submitted for Approval. Only at the PO approval time, system will validate the total releases amount against " Amount Agreed". If total releases more than "Amount Agreed", PO will not get approved.
