UBL-CR-105
What does UBL-CR-105 mean? A UBL invoice should not include the ContractDocumentReference DocumentDescription
Why did my invoice fail UBL-CR-105?
EN 16931 states that a UBL invoice should not include the cbc:DocumentDescription child of cac:ContractDocumentReference. In the core invoice model this element carries the contract reference (BT-12), for which the core model only uses the document identifier (cac:ContractDocumentReference/cbc:ID), so cbc:DocumentDescription 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 ContractDocumentReference DocumentDescription
Common causes
- A description of the referenced document is exported as cbc:DocumentDescription, although the core model does not use it on the contract reference.
- A mapping copied from AdditionalDocumentReference (where a description is used) is reused for the contract reference.
