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 AT&T (New ISA ID: 108024050B2B). Compare other AT&T Inc. channels before reusing a mapping.

  2. Map records and assign owners

    Start with purchase order or sales order, purchase-order response, shipment notice (ASN). 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 AT&T Inc. 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.
