Tesco: EDI implementation plan

Plan the business records your ERP or warehouse needs to exchange with Tesco, using the grocery retailer examples below.

A verified document list for Tesco is not available here. These are planning examples; confirm the required documents with the partner before implementation.

Document examples to confirm with your partner
Document or decisionRecord and matching IDsWhat to test
X12 850 Purchase OrderPlanning example; partner requirement unconfirmed purchase order or sales order

X12 860 Purchase Order Change Request Buyer InitiatedPlanning example; partner requirement unconfirmed buyer order-change request

original purchase order, change revision and affected line
  • 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.
X12 855 Purchase Order AcknowledgmentPlanning example; partner requirement unconfirmed purchase-order response

original purchase order, response revision and order line
  • Test a partially accepted order with a backordered line and retain both outcomes.
  • Do not treat a syntax acknowledgment as acceptance of price, quantity or delivery dates.
X12 856 Ship Notice ManifestPlanning example; partner requirement unconfirmed shipment notice (ASN)

shipment, order, package and item references
  • Reconcile item quantities through shipment, order and packaging levels against the physical shipment.
  • Test split shipments for one purchase order and prevent the second ASN from replacing the first.
X12 810 InvoicePlanning example; partner requirement unconfirmed accounts-receivable or accounts-payable invoice

invoice number, purchase order and invoice line
  • Reconcile line amounts, allowances, charges and tax to the invoice total.
  • Submit the same invoice twice and verify that it cannot create a second payable.
X12 852 Product Activity DataPlanning example; partner requirement unconfirmed product activity report

item, location, activity type and reporting period
  • Keep sales, returns and stock movements in separate measures.
  • Replace a corrected reporting period without counting the original activity twice.

Implementation steps

  1. Choose the trading account and channel

    Ask Tesco for the supplier or customer account, business unit, implementation guide and testing contact. Record what still needs confirmation before work starts.

  2. Map records and assign owners

    Start with purchase order or sales order, buyer order-change request, purchase-order response. 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 Tesco 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 EDI 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.

FAQ

Tesco EDI questions

Which EDI documents are listed for Tesco?

This entry does not include a verified Tesco document list. The suggested X12 850 Purchase Order, X12 860 Purchase Order Change Request Buyer Initiated, X12 855 Purchase Order Acknowledgment, X12 856 Ship Notice Manifest, X12 810 Invoice, X12 852 Product Activity Data documents are planning examples; their use by the partner is unconfirmed. Request the current partner guide and sample exchanges before implementation.

How should I choose the Tesco EDI channel?

Obtain the business-unit name, supplier/customer number, implementation guide and transport contact from Tesco. Confirm the connection method with the partner’s EDI contact.

Which identifiers should the Tesco mapping preserve?

For X12 850 Purchase Order, plan around buyer purchase order, order line and trading-party identifiers. For X12 860 Purchase Order Change Request Buyer Initiated, use original purchase order, change revision and affected line. Use the partner guide to locate these values and check their allowed formats.

Does a successful EDI receipt mean Tesco 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 Tesco 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.
