Implementation steps

  1. Choose the trading account and channel

    Confirm the supplier or customer account, sender and receiver IDs, test environment and current guide for Marine Corps Exchange. Compare other MCX (Marine Corps Exchange) channels before reusing a mapping.

  2. Map records and assign owners

    Start with purchase order or sales order, shipment notice (ASN), accounts-receivable or accounts-payable invoice. 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 MCX (Marine Corps Exchange) production handoff and save the results of each approved test.

  4. Check results after launch

    Match records between systems using buyer purchase order, order line and trading-party identifiers. 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.
