The Home Depot EDI
integration guide.

payment reference, invoice references and amounts applied

• Allocate a partial payment across several invoices and preserve the remaining balances.
• Keep receipt of remittance information distinct from confirmation that funds settled.

buyer purchase order, order line and trading-party identifiers

• 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.

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.

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.

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.

message reference, subject and related business document

• Preserve line breaks and readable content in the receiving work queue.
• Test an urgent message linked to an order and assign a human owner instead of silently filing it.

adjustment reference, original invoice and reason

• Test opposite credit/debit signs and verify their ledger effect.
• Apply a partial adjustment to the correct invoice line while preserving the original invoice.

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.

item, location, quantity type and snapshot time

• Distinguish on-hand, available and reserved quantities before publishing availability.
• Deliver an old snapshot after a new one and prevent stale stock from replacing current values.

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.

original load reference, carrier and response

• Associate acceptance with the correct version of the load tender.
• Test a declined tender and ensure it returns to dispatch for reassignment.

shipment reference, event code, event time and location

• Deliver an older status after a newer one and retain event history without moving the current status backward.
• Send one milestone twice and avoid duplicate customer notifications.

carrier invoice, shipment reference and charge line

• Separate line-haul, fuel and accessorial charges before comparing the invoice with the agreed rate.
• Test a second invoice for the same shipment and distinguish a revision from a duplicate.

load reference, pickup and delivery stop identifiers

• Send an amended pickup appointment and retain the previous tender decision.
• Test a multi-stop load whose stop sequence differs from address sorting.
