BR-42

Checked against Peppol BIS Billing 3.0 2026.5
What does BR-42 mean? Each Invoice line allowance (BG-27) shall have an Invoice line allowance reason (BT-139) or an Invoice line allowance reason code (BT-140).
Why did my invoice fail BR-42?
Every Invoice line allowance (BG-27) must be justified by either a free-text line allowance reason (BT-139) or a coded line allowance reason (BT-140), with at least one present. This explains why the discount was applied to that particular line.
Official rule text
Each Invoice line allowance (BG-27) shall have an Invoice line allowance reason (BT-139) or an Invoice line allowance reason code (BT-140).
Common causes
- Line allowance added with amount but no reason text or reason code
- Reason available in source data but not mapped into the line's AllowanceCharge
- Empty cbc:AllowanceChargeReason element emitted
How do I fix it?
Provide a reason and/or reason code on the line allowance: <cac:AllowanceCharge><cbc:ChargeIndicator>false</cbc:ChargeIndicator>...<cbc:AllowanceChargeReasonCode>95</cbc:AllowanceChargeReasonCode><cbc:AllowanceChargeReason>Volume discount</cbc:AllowanceChargeReason></cac:AllowanceCharge>
