What it means
This rule checks that no document-level cac:TaxTotal/cac:TaxSubtotal in a UBL invoice or credit note contains cbc:TierRange. In the VAT breakdown (BG-23), the taxable amount (BT-116) and any applicable VAT rate (BT-119) are separate fields, not a tier range.
Why it matters
EN 16931 does not use tier ranges in document-level tax subtotals.
How to fix it
Delete cbc:TierRange from each document-level cac:TaxTotal/cac:TaxSubtotal. Ask the supplier of your invoicing software to stop writing the element if you cannot change it yourself. Recheck the file.
