Purchase orders automatically changing from "Full Match" to "Don't Match"

Hello,

We are seeing scenarios where the purchase order is being raised on the incorrect supplier bank location which is causing the PO to default to that locations currency.

When it has realised the PO is in the incorrect currency, the business is manually updating the PO location and currency via Add/Update PO page.

This is then changing the matching flag from "Full Match" to "Don't Match". As this is not spotted by the business at the time, we have had voucher be processed without matching required.

Attached is a document which outlines the scenario of the matching flag changing to "Don't Match". We would expect this to stay as "Full Match".
