# BR-14 Invoice total amount with VAT is required

An invoice shall have the Invoice total amount with VAT (BT-112): the invoice total including VAT, before any amount already paid (BT-113) is deducted.

## Problem Description

> **ERROR**: EN 16931 core business rule (CEN)

## Context and Significance

This is an EN 16931 core rule. BT-112 is BT-109 plus the invoice total VAT amount (BT-110), as checked by BR-CO-15. The amount due for payment (BT-115) is derived from it and differs from BT-112 when part of the invoice was paid in advance. The error appears when an export writes only the payable amount and treats it as the total with VAT. In CII, BT-112 is ram:GrandTotalAmount.

## Solution

Add cac:LegalMonetaryTotal/cbc:TaxInclusiveAmount equal to BT-109 plus the total VAT amount (BT-110).
