What this rule requires
The rule requires that in a UBL Invoice or CreditNote, at least one of the elements cbc:BuyerReference or cac:OrderReference/cbc:ID is present. A document fails validation if neither element appears. The rule does not require both; either one suffices.
How to fix
Ensure the invoice or credit note contains either a cbc:BuyerReference element with the buyer reference value, or a cac:OrderReference element containing a cbc:ID element with the purchase order reference value, or both.
