Tesco-Specific Requirements

Tesco has precise
requirements for suppliers.

Tesco's EDI compliance is not generic. GLNs, SSCC pallet labels, depot routing codes, and booking-in windows all need to be correct before your first delivery is accepted. Supply Lens is configured for Tesco's specific rules, not a generic EDI template.

GS1 GLN identifiers

Every Tesco location (RDC, depot, or store) has a GS1 Global Location Number. Supply Lens maps Tesco's GLNs to your internal warehouse and customer references so documents route correctly every time.

SSCC pallet labels

Tesco requires GS1-compliant SSCC (Serial Shipping Container Code) labels on all pallets. Supply Lens generates SSCC references as part of the DESADV — so your despatch advice and physical labels are always in sync.

RDC depot routing

Tesco's UK network routes through Regional Distribution Centres including Daventry, Hinckley, Livingston, Magor, and others. The correct RDC is determined per order and mapped in the DESADV so deliveries arrive at the right location.

EAN-to-item code mapping

Tesco identifies products by GS1 EAN / GTIN. Supply Lens maintains a cross-reference table mapping Tesco EANs to your own product or item codes so the PO lands correctly in your system regardless of the code Tesco sends.

Invoice tolerance rules

Tesco applies strict invoice matching rules. Price, quantity, and date tolerances must be met. Supply Lens checks invoice values against the original PO and flags discrepancies before submission, reducing deductions and charge-backs.

Tesco ROI specifics

Tesco Ireland operates as a separate trading entity with its own GLNs, supplier codes, and document routing. Supply Lens handles UK and ROI as distinct configurations so the same integration supports both without mixing data or references.

Document Flow

Every document.
Every direction.
Automatically.

Supply Lens handles the full Tesco EDI message set — inbound and outbound — so no document is ever manually produced, re-keyed, or sent late.

  • ORDERS — Tesco purchase orders received and validated
  • DESADV — Despatch advice / ASN transmitted on dispatch
  • RECADV — Goods received confirmation inbound from Tesco on delivery
  • INVOIC — Invoice submitted with correct Tesco GLN and tax treatment
  • Credit notes raised and transmitted when returns or claims occur
  • All documents formatted to Tesco's EDIFACT message specifications

Location & Product Cross-Reference

Pre-configured.
Resolved automatically
on every order.

Tesco uses its own depot codes, GLN references, and product identifiers. Supply Lens ships with all Tesco location data pre-loaded — UK RDCs, ROI depots, and store GLNs — so routing is resolved automatically from the moment your first order arrives. Product cross-referencing works the same way: your products are imported once, and the workflow maps Tesco EANs to your internal item codes on every document without manual intervention.

  • All Tesco UK and ROI depot codes pre-configured — no manual setup required
  • Location cross-reference resolved automatically during order processing
  • Product EANs matched to your item codes within the workflow
  • Pack-size variants, promotional lines, and multipacks handled separately
  • Depot code changes updated on our side — your integration keeps running

Configuration

Configured for
Tesco. Connected
to your system.

Supply Lens holds Tesco's rules so you don't have to. Your team provides credentials, product mappings, and confirms your depot routes — everything else is handled at the Supply Lens layer.

1

Tesco supplier onboarding

Your Tesco supplier number, GLN, and EDI connection details are captured and configured as the inbound/outbound channel.

2

Product import and cross-reference

Your products are imported into Supply Lens. The workflow then handles Tesco EAN-to-item-code cross-referencing automatically — including pack-size and promotional variants.

3

Location cross-reference

All Tesco depot codes and GLNs are pre-loaded. The workflow resolves the correct RDC or store on every incoming order — UK and ROI handled as separate paths automatically.

4

ERP connection and go live

Your ERP or IMS is connected. Orders flow end-to-end — purchase order in, DESADV and INVOIC out — with no manual steps required.

Tesco Edge Cases

The situations that
catch suppliers out.

Tesco's EDI compliance requirements are strict. Supply Lens handles the scenarios that typically cause rejections, deductions, or failed deliveries.

"Tesco sent a PO with an EAN we haven't mapped yet — it's a new product line."

Unrecognised EANs go to an exception queue immediately. The PO is held, your team is notified with the full context, the mapping is added, and the order is re-triggered. No silent drop, no delayed acknowledgement that breaches Tesco's response window.

"We shipped 44 cases but the PO was for 48. The DESADV needs to show what actually left the warehouse."

Partial despatch is handled cleanly. The DESADV reflects the actual quantity shipped with the correct SSCC references. Where Tesco sends a RECADV confirming a short receipt, Supply Lens matches it against the open order so your ERP and Tesco's records stay aligned.

"We supply both Tesco UK and Tesco ROI — they keep getting mixed up in our system."

UK and ROI are maintained as completely separate trading partner configurations in Supply Lens — different GLNs, different supplier codes, different depot routing, different document series in your ERP. The integration keeps them isolated so they can never cross-contaminate.

"Tesco raised a deduction because our invoice price didn't match the PO to the penny."

Invoice values are validated against the original PO price and agreed price lists before submission. Discrepancies are flagged before the INVOIC is sent — giving your team the chance to correct or query rather than receive a Tesco charge-back weeks later.

Getting Set Up

What you need
to go live with Tesco.

Tesco EDI onboarding involves their supplier team, your EDI connection, and your internal product and depot data. Supply Lens manages the configuration — you provide the inputs.

  • Tesco supplier number and GLN
  • EDI connection details — AS2 credentials or VAN endpoint
  • ERP or IMS credentials (Unleashed, CIN7, Enterpryze, or other)
  • Tesco ROI supplier code if applicable
  • Sample Tesco POs (real examples where available)
  • Invoice price list for validation rules
