UBL-CR-111
What does UBL-CR-111 mean? A UBL invoice should not include the AdditionalDocumentReference UUID
Why did my invoice fail UBL-CR-111?
EN 16931 states that a UBL invoice should not include the cbc:UUID 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:UUID 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 UUID
Common causes
- The ERP exports its internal GUID for the referenced document as cbc:UUID instead of putting the reference in cbc:ID.
- A mapping template fills both cbc:ID and cbc:UUID with the same identifier 'to be safe'.
