What does UBL-SR-34 mean? Invoice line note shall occur maximum once
Why did my invoice fail UBL-SR-34?
An invoice line (BG-25) may include one Invoice line note (BT-127), a free-text remark about that specific line. EN 16931 allows at most one note per line, so cbc:Note must not occur more than once within a single cac:InvoiceLine (or cac:CreditNoteLine). Multiple remarks must be combined into a single note.
Official rule text
Invoice line note shall occur maximum once
Common causes
- A template emits separate cbc:Note elements per remark on the same line.
- Line-level comments split across multiple cbc:Note elements.
- Copy of both an internal and a printed note as two notes on the line.
How do I fix it?
Combine into one note per line: <cac:InvoiceLine>...<cbc:Note>Backordered; ships next week</cbc:Note>...</cac:InvoiceLine>.
