The allowed maximum number of decimals for the Document level charge base amount (BT-100) is 2.
Document level charge base amount (BT-100) is written with more than 2 decimal places.
Round BT-100 to 2 decimals before serialising it. This is a formatting rule, not an arithmetic one - the value itself is usually right, the XML just carries extra digits from a float. Format the amount as a fixed-point decimal string.
CII — context $Document_level_charges
string-length(substring-after(../ram:BasisAmount,'.'))<=2
UBL — context cac:AllowanceCharge[cbc:ChargeIndicator = true()]
string-length(substring-after(cbc:BaseAmount,'.'))<=2
Nothing is stored, and the whole invoice is checked, not just this rule. A PDF only works if it is Factur-X / ZUGFeRD — a PDF with the invoice XML inside it.
