Reason code MUST be according to UNCL 7161 D.16B.
What does this rule mean?
The charge reason code is not from UNCL 7161 D.16B.
Peppol narrows the EN 16931 code lists further so every receiver on the network can resolve the value without a prior agreement.
Official rule message (standard)
Reason code MUST be according to UNCL 7161 D.16B.
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:AllowanceCharge[cbc:ChargeIndicator = 'true']/cbc:AllowanceChargeReasonCode
CII
ram:SpecifiedTradeAllowanceCharge[normalize-space(ram:ChargeIndicator/udt:Indicator) = 'true']/ram:ReasonCode
