Choose the starting event and owner
Decide which application acts when a seller responds to an order. Name the operational owner of the purchase-order response and the team that resolves rejected or ambiguous messages.
-
Keep record IDs connected
Map original purchase order, response revision and order line. Confirm qualifiers, code lists, units and date/time meaning against the agreed X12 version and Tepperman's guide. Preserve the source reference alongside any new destination identifier.

Run the failure cases in the mapping table against realistic purchase-order response data. Check how the receiving system reports a rejection and how your team corrects it without creating a duplicate.
