How to default Requester on AP Invoice Header from PO - For AME purpose

Dear All

We are working on AME for AP Invoice approval. To initiate workflow, requester field at AP invoice Header must be populated. This field is non mandatory.

If we have AP Invoice matched with PO, can we default requester from PO Distribution ? I mean PO has requester on it. If I select PO in AP Invoice Header screen, it defaults the supplier, supplier sites etc.

Is there any way that we can default the Requester from PO ?

Can someone help me on this?

Thanks & regards
