field3 rules
Every EN 16931, Peppol and XRechnung rule that constrains BT-139. If one of them fails, the others are usually worth a look — a wrong value in one field tends to break several checks at once.
| BR-42 | fatal | Each Invoice line allowance (BG-27) shall have an Invoice line allowance reason (BT-139) or an Invoice line allowance reason code (BT-140). |
| BR-CO-07 | fatal | Invoice line allowance reason code (BT-140) and Invoice line allowance reason (BT-139) shall indicate the same type of allowance reason. |
