Function Module to copy purchase order to another order

Question

I'm creating documents using the function module BAPI_PO_CREATE1 and modifying documents using BAPI_PO_CHANGE to update some parts of the purchase order.

I need to create two orders with the same purchase order lines, one for purchasing and another for transferring.

I can do it calling BAPI_PO_CREATE1 twice with the same POITEMs. Is there a function module to create a copy of a purchase order using a reference number (PO_NUMBER) and a modified header?

Answer 1

I think you could use BAPI_PO_CREATE1 using fields PREQ_NO and PREQ_ITEM from POITEM structure. Just ensure you have update structure POITEMX with these fields...

Try it out and let me know.
