CVS EDI
integration guide.

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, 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.

original document reference, error location and response status

• Return an error for one line and associate it with that line rather than rejecting unrelated records.
• Keep application acceptance distinct from transport receipt and syntax acknowledgment.

schedule, item, location and time bucket

• Keep forecast quantities separate from firm releases in the receiving planning system.
• Replace an overlapping planning horizon without adding the old and new forecasts together.

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.

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.

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.
