What does UBL-SR-46 mean? Payment means text shall occur maximum once
Why did my invoice fail UBL-SR-46?
The Payment terms (BG-16 / BT-20) is free-text describing conditions such as discounts or penalties, carried as cac:PaymentTerms/cbc:Note. EN 16931 allows the payment terms text to appear at most once. A single terms note avoids conflicting or duplicated conditions.
Official rule text
Payment means text shall occur maximum once
Common causes
- More than one cac:PaymentTerms element with a cbc:Note is present.
- A cac:PaymentTerms block containing a Note was duplicated when adding a settlement discount.
- Concatenating terms from multiple sources produced separate Note elements instead of one.
How do I fix it?
Consolidate into a single note: <cac:PaymentTerms><cbc:Note>Net 30 days; 2% discount if paid within 10 days</cbc:Note></cac:PaymentTerms>.
