EN 16931Error
The invoice has an invoice line (BT-151) with VAT category AE (Reverse charge) but does not identify the taxable parties: it must contain a seller identifier (VAT id BT-31, tax registration id BT-32 or tax representative VAT id BT-63) AND a buyer identifier (VAT id BT-48 or legal registration id BT-47); a reverse-charge invoice without the buyer's VAT id is the most common cause. Fill cac:PartyTaxScheme/cbc:CompanyID / ram:SpecifiedTaxRegistration/ram:ID accordingly.
