Warning

UBL-CR-632: A discount identifier does not belong inside the line price

In short

Warning: worth checking.

UBL-CR-632 means a cac:AllowanceCharge block inside an invoice or credit note line's price contains an identifier (cbc:ID). Remove that identifier, not the price discount amount (BT-147) or the price before the discount (BT-148).

On this page

What it means

The rule checks every cac:Price/cac:AllowanceCharge on invoice and credit note lines for cbc:ID. It applies regardless of the block's charge indicator. It does not check identifiers in discount or charge blocks directly under a line or the document.

Why it matters

EN 16931 does not define an identifier for a price discount.

How to fix it

Remove cbc:ID from cac:AllowanceCharge inside cac:Price in each affected cac:InvoiceLine or cac:CreditNoteLine. Keep any valid price discount amount (BT-147) and price before the discount (BT-148), which excludes VAT. If you need to keep the identifier as a reference, use the line note (BT-127). Export the corrected file and recheck it.
