Confirm the business unit and account before copying a mapping from another channel. 2. #### Map records and assign owners Start with buyer order-change request, purchase order or sales order, payment or remittance record. 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. 3. #### Test a complete exchange 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. 4. #### Check results after launch 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. ### Go-live checklist - The required X12 documents, versions and sample files are agreed. - Sender and receiver IDs, test connections and production connections are agreed with the channel owner. - Delivery receipts, document validation and business responses have monitoring and a named owner. - Tests cover duplicates, partial processing and reconciliation with realistic business records. ### Related documents and resources - [Field mapping workbook](https://www.stacksync.com/blog/two-way-sync-field-mapping-workbook) - [Production readiness checklist](https://www.stacksync.com/blog/two-way-sync-production-readiness-checklist) - [Evaluate your integration requirements](https://www.stacksync.com/blog/integration-evaluation-worksheet) **Sources.** Directory data as of 2026-05-07.

X12 860 Purchase Order Change Request Buyer Initiated; X12 850 Purchase Order; X12 820 Payment Order Remittance Advice; X12 824 Application Advice; X12 810 Invoice; X12 856 Ship Notice Manifest; X12 990 Response To A Load Tender; additional documents are shown in the mapping plan. Confirm which documents, directions and versions apply to your account. ### How should I choose the Costco EDI channel? The directory lists 12 channels for Costco, including Costco Wholesale (Canada), Costco Merchandise US - Direct (IBM) - NEW, Costco Merchandise Canada - Direct (IBM)(OLD), Costco Merchandise US - Direct via IBM VAN (OLD). Match the channel to your actual trading relationship and compare its document list before reusing a mapping. ### Which identifiers should the Costco mapping preserve? 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. ### Does a successful EDI receipt mean Costco accepted the business document? 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. ### What should be tested before launching Costco EDI? 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. ## Your last integration took months.
