Start with buyer order-change request, purchase order or sales order, application validation result. For each document, assign the source system, destination record, stable identifiers and person responsible for exceptions. Agree whether a change updates an existing record or creates a new event.
Run a successful exchange and the failure cases in the mapping table. Track delivery, document validation and processing in your business system separately. Agree on the Costco production handoff and save the results of each approved test.
Match records between systems using original purchase order, change revision and affected line. Assign an owner to missing responses, duplicates and rejected records. Test recovery before enabling automatic retries.

For X12 860 Purchase Order Change Request Buyer Initiated, plan around original purchase order, change revision and affected line. For X12 850 Purchase Order, use buyer purchase order, order line and trading-party identifiers. Use the partner guide to locate these values and check their allowed formats.
Track delivery, document validation and business processing separately. An AS2 message disposition notification (MDN) confirms transport receipt; an X12 997 or 999 reports technical validation. Use the agreed business response or reconciliation report to confirm that the order, shipment or invoice was processed.
Apply a quantity reduction to the existing order instead of creating another order. Test a cancellation arriving after allocation or shipment and route it to an exception owner. Also test missing responses and recovery after a destination failure. Assign an owner to each failure and obtain partner approval before launch.
