Fill in BSEG-ZUONR with PO BEDNR field
I have a requirement to filled in BSEG-ZUONR field with BEDNR field in PO line item through MIGO and MIRO. I'm not able to find any user exit to change the value in BSEG-ZUONR. Currently ZUONR is filled with PO # and line item.
Is there any suggestion on how to change the value ZUONR with BEDNR?
