BR-DEC-17 Rounding amount must not exceed two decimal places

The BT-114 Rounding amount is limited to a maximum of two decimal places. Any value carrying three or more fractional digits fails EN16931 validation.

Problem Description

ERROR

EN 16931 decimal precision rule (BR-DEC)

Context and Significance

This is an EN16931 core decimal-precision constraint enforced by KoSIT: every monetary amount in the invoice must be expressed with no more than two decimals.

Solution

Round BT-114 to two decimal places before serialising the amount, and apply the same rounding used in the BR-CO total and sum calculations so the invoice still reconciles.
