UBL-CR-110
What does UBL-CR-110 mean? A UBL invoice should not include the AdditionalDocumentReference CopyIndicator
Why did my invoice fail UBL-CR-110?
EN 16931 states that a UBL invoice should not include the cbc:CopyIndicator child of cac:AdditionalDocumentReference. In the core invoice model this element carries additional supporting documents (BG-24), which only support the identifier, document type code, description and attachment defined by the core model, so cbc:CopyIndicator lies outside the standard's subset of UBL and validators flag its presence. It is a warning-level cardinality rule: the extra data is ignored by receivers that implement only the core model.
Official rule text
A UBL invoice should not include the AdditionalDocumentReference CopyIndicator
Common causes
- The generating software copies a full UBL DocumentReference structure from an order or despatch message that legitimately uses cbc:CopyIndicator.
- A generic UBL library serialises every optional field of the DocumentReference aggregate by default.
