field2 rules
Every EN 16931, Peppol and XRechnung rule that constrains BT-146. 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-26 | fatal | Each Invoice line (BG-25) shall contain the Item net price (BT-146). |
| BR-27 | fatal | The Item net price (BT-146) shall NOT be negative. |
