Official rule message (standard)

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:InvoiceLine/cac:AllowanceCharge[cbc:ChargeIndicator = false()] | //cac:CreditNoteLine/cac:AllowanceCharge[cbc:ChargeIndicator = false()]

CII

  • //ram:SpecifiedLineTradeSettlement/ram:SpecifiedTradeAllowanceCharge/ram:ChargeIndicator[udt:Indicator = 'false']

Technical test

The rule passes when this Schematron expression holds true:

(../ram:Reason) or (../ram:ReasonCode)
