EN 16931Error
A line, allowance or charge uses VAT category AE (Reverse charge; category AE means reverse charge: the buyer accounts for the VAT, so the invoice shows 0 % and 0.00 VAT), but the VAT breakdown (BG-23) contains no entry with category AE (exactly one is required). Usually the line was coded AE but the breakdown was built with a different category; the sender must add a cac:TaxSubtotal / ram:ApplicableTradeTax with category AE or fix the line's category (BT-151/BT-95/BT-102).
