Original rule text
[UBL-SR-31]-Document level charge reason shall occur maximum once
(count(cbc:AllowanceChargeReason) <= 1)UBL-SR-31 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 requires that a document-level cac:AllowanceCharge with cbc:ChargeIndicator = true() contains at most one cbc:AllowanceChargeReason. A document fails when such a charge has more than one cbc:AllowanceChargeReason element.
How to fix
Ensure each document-level charge (cac:AllowanceCharge where cbc:ChargeIndicator is true) has only one cbc:AllowanceChargeReason. Remove any extra reason elements from that charge, or adjust the system to output a single reason.
