What this rule requires
The rule requires that in each cac:PaymentMeans element, the cac:PaymentMandate/cbc:ID element occurs at most once. A document fails this fatal validation rule if any cac:PaymentMeans contains more than one cac:PaymentMandate/cbc:ID.
How to fix
Ensure each cac:PaymentMeans contains no more than one cac:PaymentMandate/cbc:ID. If there are multiple such elements, remove the extras so that only one remains, or adjust the generating system to output at most one mandate reference identifier per payment means.
