MRP Planned Purchase Order - Agreement price


We are using the purchase agreement and purchase order workflow in AX 2012 R2.

We don’t have a problem with Normal purchase creation, it’s picked from the agreement and gets approved as per the workflow setup.

Master planning, Planned purchase orders not getting agreement value while firming, it picks zero value and directly get’s approved.

the problem arises if they amend the purchase orders which are firmed from MRP. it’s stuck in review status since without agreement value purchase order will not get approved.

Any idea how to overcome this issue.
