EN 16931Error

Invoice total with VAT (BT-112) must equal invoice total without VAT (BT-109) plus total VAT amount (BT-110). The sender must recompute cbc:TaxInclusiveAmount / ram:GrandTotalAmount (check rounding: both operands are two-decimal amounts).

This is a property of the file you received, so it cannot be corrected on your side without changing the document — ask the supplier to reissue it.

Worked example · UBL

BT-112 is net plus VAT: 314.86 + 22.04 = 336.90. A gross total of 336.00 does not match the VAT total of the same document.
