field3 rules
Every EN 16931, Peppol and XRechnung rule that constrains BT-145. 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-44 | fatal | Each Invoice line charge shall have an Invoice line charge reason or an invoice line allowance reason code. |
| BR-CO-08 | fatal | Invoice line charge reason code (BT-145) and Invoice line charge reason (BT-144) shall indicate the same type of charge reason. |
| BR-CO-24 | fatal | Each Invoice line charge (BG-28) shall contain an Invoice line charge reason (BT-144) or an Invoice line charge reason code (BT-145), or both. |
