Implementation steps

  1. Choose the trading account and channel

    Choose among AT&T (Legacy ISA ID: 108024050NHP), AT&T (New ISA ID: 108024050B2B). Confirm the business unit and account before copying a mapping from another channel.

  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.

How should I choose the AT&T Inc. EDI channel?

The directory lists 2 channels for AT&T Inc., including AT&T (Legacy ISA ID: 108024050NHP), AT&T (New ISA ID: 108024050B2B). Match the channel to your actual trading relationship and compare its document list before reusing a mapping.

Which identifiers should the AT&T Inc. mapping preserve?

For X12 850 Purchase Order, plan around buyer purchase order, order line and trading-party identifiers. For X12 855 Purchase Order Acknowledgment, use original purchase order, response revision and order line. Use the partner guide to locate these values and check their allowed formats.

Does a successful EDI receipt mean AT&T Inc. 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 AT&T Inc. EDI?

Map buyer item numbers to seller SKUs and explicitly convert case quantities to the agreed unit. Resend one purchase order and confirm that only one sales order is created. Also test missing responses and recovery after a destination failure. Assign an owner to each failure and obtain partner approval before launch.
