We have EDI X12 messges from customers. 850 PO is coming with REF**ZZ** 230 segment . This 230 we want to copy it in our sales order which 850 message will create and we want to pass this 230 value from sales order to Invoice. From invoice 810 message outbound from invoice should carry 230 back to customer.
We do not want to copy 230 via text in our sales order since that would involve config of text determination.
Q1) In which segment of ORDERS Idoc message can we populate the above REF segment value 230 and where will that 230 value in Sale order be copied so that it is copied to delivery and invoice ?
Q2) In which segment of INVOIC Message idoc type from SAP, should we include 230 and which EDI segment should we map it to ?
