What does UBL-SR-50 mean? Item description shall occur maximum once
Why did my invoice fail UBL-SR-50?
The Item description (BT-154) is free-text giving further detail about the invoiced item, carried as cac:InvoiceLine/cac:Item/cbc:Description. EN 16931 permits at most one description per item. More than one would make the item's descriptive text ambiguous.
Official rule text
Item description shall occur maximum once
Common causes
- An invoice line's cac:Item contains two or more cbc:Description elements.
- Multi-language or multi-part descriptions were emitted as separate Description elements.
- A merge of catalog data produced duplicate Description nodes.
How do I fix it?
Combine into one element: <cac:Item><cbc:Description>Ergonomic office chair, black, adjustable</cbc:Description>...</cac:Item>.
