integration guide.

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.

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 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 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.

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.

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.

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.
