BR-DEC-10 The sum of document-level allowances may have at most two decimals
noun · EN 16931 · fatal · BT-107
For a sample invoice, the library reports: The allowed maximum number of decimals for the Sum of allowances on document level (BT-107) is 2, but you declared 10.005, which has 3.
- Business term
BT-107- Severity
fatal
The fix
Round declaredTotals.allowanceTotalAmount to two decimals (10.01 here) using half-up rounding away from zero, for which this package exports round2(). Alternatively drop declaredTotals and let the library compute the totals, which it always rounds correctly.

"message": "The allowed maximum number of decimals for the Sum of allowances on document level (BT-107) is 2, but you declared 10.005, which has 3. The rule is written against the serialised value — the schematron counts the characters after the decimal point in the XML — so the check is about what gets written, not about what the number \"really\" is. A total that carries extra decimals when its parts do not means the parts were added before they were rounded. EN 16931 requires the other order — round each document level allowance amount (BT-92) to two decimals, then sum.",

xpath is always a UBL path. On a CII invoice, look for the
matching CII field instead.
