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, 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, 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.

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.

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.

routing request, purchase order and ready-to-ship date

• Test an order split into two pickups and keep each routing request distinct.
• Handle a changed ready date while the original routing request is still open.

routing reference, order and shipment

• Match instructions to the correct open routing request.
• Test a carrier reassignment after warehouse planning and require the shipping record to be updated.

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.

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.

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.

return authorization, original order and returned item

• Test a return quantity larger than the original shipment and require review.
• Keep authorization separate from physical receipt so stock is not increased early.
