What this rule requires
The rule requires that the invoice total amount without VAT (BT-109), given in cbc:TaxExclusiveAmount (UBL) or ram:TaxBasisTotalAmount (CII), has no more than two digits after the decimal point. The test checks the length of the part after . and fails if it is longer than 2, for example 123.456 fails while 123.45 passes.
How to fix
