BR-S-03 Standard-rated document allowance requires a seller tax identifier

An invoice that contains a document level allowance (BG-20) whose document level allowance VAT category code (BT-95) is "Standard rated" shall contain the Seller VAT identifier (BT-31), the Seller tax registration identifier (BT-32) and/or the Seller tax representative VAT identifier (BT-63).

Problem Description

ERROR

EN 16931 VAT category rule

Context and Significance

This EN16931 rule is the counterpart of BR-S-02 for document level allowances with category S. It fails even when no invoice line uses category S, as long as one document level allowance does. In practice, the error appears when a volume or loyalty discount is exported at document level with category S while the seller party carries no tax identifier.

Solution

Provide the seller VAT identifier (BT-31), tax registration identifier (BT-32) or tax representative VAT identifier (BT-63) whenever a document level allowance uses category S.
