Supplier Sales Order Number Field for Requisition Imports

Hi Experts,

There is a request from a supplier to include the "Supplier Sales Order Number" for all Bill Only POs transmitted via EDI to them. Currently, our process involves importing the requisitions from a boundary system to create the Bill Only POs in Oracle, which are then sent via EDI to an intermediary. The third party then transforms the 850 XML document into X12 format for the supplier.

The supplier has indicated that there will be one "Supplier Sales Order Number" for all the PO lines and that the value should be captured on the PO Header. Also, the supplier expects the value to be retrieved from the header in the REF>VN segment in their transformed document (see the attached screenshot).
