Getting Error: Please undo the changes to the document in the current revision, When Attempting To Cancel A Purchase Order Line Updated With A New Tax Code (Doc ID 1306172.1)

Symptoms

When attempting to Cancel PO line that was updated with a new Tax Code,
the following error occurs.

ERROR
---------------
Please undo the changes to the document in the current revision before taking the cancel action.

Cause: You are trying to cancel a document that has been altered since its last archived revision.

Action: You must first undo the changes before you can cancel the document.

Due to this issue, users cannot cancel the PO line once the tax code has been amended.
The Buyer can use ‘Final Close’ to clear the encumbrance however the printed purchase order does not reflect the cancellation and it can be misleading to the vendor.

Steps to reproduce:
-------------------

1. Responsibility:  PO Buyer.

2. Find existing open PO with a tax code associated to a PO line.
   - Open the purchase order.
   - Unreserve the PO.
   - Update the tax code to a different tax code.
   - Reapprove the PO.

3. Attempt to cancel the PO using either the Purchase Order or Purchase Order Summary screen.
