EN 16931Error
The invoice has a document level charge (BT-102) with VAT category O (category O means the supply is outside the scope of VAT altogether (no VAT law applies, e.g. seller not VAT-registered)) but still carries a seller VAT id (BT-31), tax representative VAT id (BT-63) or buyer VAT id (BT-48). Either the category is wrong (a VAT-registered seller should use S, Z, E, AE, K or G) or the VAT identifiers must be removed.
