Warning

UBL-CR-625: A price change reason does not belong on the line price

In short

Warning: worth checking.

UBL-CR-625 means the price on an invoice or credit note line contains a price change reason (cbc:PriceChangeReason), which EN 16931 does not use there. Remove the element from cac:Price. If you need to keep the explanation, write it in the line note or item description.

What it means

The price block of each line (cac:Price) holds the unit price (BT-146) and the quantity that price applies to (BT-149). The rule checks that this block has no cbc:PriceChangeReason, free text explaining why the price changed, for example a price rise or a special offer.

Why it matters

EN 16931 has no separate price change reason field within the line price.

How to fix it

Remove cbc:PriceChangeReason from cac:Price in each affected cac:InvoiceLine or cac:CreditNoteLine. If you need to keep the explanation, write it in the line note (BT-127) or item description (BT-154). Export the corrected file and recheck it.
