A calculation/amount rule: the figures it names must reconcile arithmetically.

Official rule message (standard)

VAT category tax amount (BT-117) = VAT category taxable amount (BT-116) x (VAT category rate (BT-119) / 100), rounded to two decimals.

Where the rule applies

Syntax: CII · UBL

The same rule, expressed twice: UBL and CII name the same fields with different paths. Running a CII file against the UBL rules is why you get errors that mean nothing.

UBL

  • cac:TaxTotal/cac:TaxSubtotal

CII

  • //ram:ApplicableHeaderTradeSettlement/ram:ApplicableTradeTax

Technical test

The rule passes when this Schematron expression holds true:

(round(.[normalize-space(upper-case(ram:TypeCode)) = 'VAT']/xs:decimal(ram:RateApplicablePercent)) = 0 and (round(xs:decimal(ram:CalculatedAmount)) = 0)) or (round(.[normalize-space(upper-case(ram:TypeCode)) = 'VAT']/xs:decimal(ram:RateApplicablePercent)) != 0 and ((abs(xs:decimal(ram:CalculatedAmount)) - 1 <= round(abs(xs:decimal(ram:BasisAmount)) * (.[normalize-space(upper-case(ram:TypeCode)) = 'VAT']/xs:decimal(ram:RateApplicablePercent) div 100) * 10 * 10) div 100 ) and (abs(xs:decimal(ram:CalculatedAmount)) + 1 >= round(abs(xs:decimal(ram:BasisAmount)) * (.[normalize-space(upper-case(ram:TypeCode)) = 'VAT']/xs:decimal(ram:RateApplicablePercent) div 100) * 10 * 10) div 100 ))) or (not(exists(.[normalize-space(upper-case(ram:TypeCode))='VAT']/xs:decimal(ram:RateApplicablePercent))) and (round(xs:decimal(ram:CalculatedAmount)) = 0))
