UBL-CR-477: Do not name the VAT category of an invoice-level discount or charge

What it means

The rule looks at the discounts (BG-20) and charges (BG-21) placed on the whole invoice, directly under the invoice or credit note. It warns when the cac:TaxCategory inside one of them has a cbc:Name. EN 16931 identifies the VAT of a discount by its category code (BT-95) and applicable VAT rate (BT-96), and that of a charge by its category code (BT-102) and applicable VAT rate (BT-103).

Why it matters

EN 16931 does not use cbc:Name in the VAT category of document-level discounts (BG-20) or charges (BG-21).

How to fix it

Delete cbc:Name from the cac:TaxCategory inside each cac:AllowanceCharge directly under the Invoice or CreditNote element. Check that the category code and any applicable VAT rate on the discount or charge match the VAT breakdown. Check the corrected file again.
