Blocking finding856_PURCHASE_ORDER_MISSINGaccount specific

Amazon 856 has no PRF purchase order

The preflight did not find a purchase-order reference in the transaction.

Fix

Make the source change, then revalidate

Add the PRF data at the hierarchy level required by the current Vendor Central guide, then reconcile it to the accepted PO.

What to inspect

Open the exact location reported by the validator. Confirm the source mapping or warehouse value rather than editing the outbound document as a one-off.

How to prevent recurrence

Add the rejected file as a sanitized regression fixture. Keep the expected finding code stable so mapping changes cannot silently reintroduce it.
