Original rule text
[UBL-SR-30]-Document level allowance reason shall occur maximum once
(count(cbc:AllowanceChargeReason) <= 1)UBL-SR-30 is a fatal rule in the schema layer of Peppol BIS Billing 3.0.20 · UBL. An invoice that breaks it is rejected.
What this rule requires
The rule applies to document-level allowance charges, i.e. cac:AllowanceCharge where cbc:ChargeIndicator is false. The test requires that there is at most one cbc:AllowanceChargeReason within such an element. A document fails this fatal rule if more than one allowance reason is present.
How to fix
In the document-level cac:AllowanceCharge[cbc:ChargeIndicator = false()], ensure that cbc:AllowanceChargeReason occurs at most once. If multiple reasons are present, remove or consolidate the extra cbc:AllowanceChargeReason elements.
