UBL-CR-073
What does UBL-CR-073 mean? A UBL invoice should not include the ReceiptDocumentReference Attachment
Why did my invoice fail UBL-CR-073?
EN 16931 states that a UBL invoice should not include the cac:Attachment child of cac:ReceiptDocumentReference. In the core invoice model this element carries the receiving advice reference (BT-15), for which the core model only uses the document identifier (cac:ReceiptDocumentReference/cbc:ID), so cac:Attachment 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 ReceiptDocumentReference Attachment
Common causes
- A file is embedded via cac:Attachment on the receiving advice reference instead of using an AdditionalDocumentReference (BG-24), the only place the core model allows attachments.
- A full UBL 2.1 document model is serialised without pruning it to the EN 16931 subset.
