WORKED EXAMPLE: PO-730 (separate from the PO-1042 sample set)
All amounts USD before tax. Item R-10: 100 each. No additional charges.
Oct 1: PO-730 revision 1, USD 8.00 each / USD 800.00; requested delivery Oct 20.
Oct 2: OC-730, USD 8.40 each / USD 840.00; proposed delivery Oct 27.
Oct 3: Authorized buyer email approves USD 8.40 only; asks to retain Oct 20.
Oct 4: PO-730 revision 2, USD 8.40 each / USD 840.00; delivery remains Oct 20.
Oct 15: INV-730, USD 8.40 each / USD 840.00; references PO-730, no revision.
These records and the buyer's authority are assumptions of this fictional exercise.

Price basis: PO-730 revision 2, supported by the Oct 3 buyer approval.
Invoice minus revision 1: 100 x (8.40 - 8.00) = +USD 40.00.
Invoice minus revision 2: 100 x (8.40 - 8.40) = USD 0.00.
Open: supplier-confirmed Oct 27 differs from requested Oct 20; no acceptance of that change.
Not reviewed: receipt, payment history, other orders or invoices.
If approval and revision 2 are missing: record +USD 40.00 against revision 1,
with acceptance unverified. Do not assume either an overcharge or acceptance.
