Peppol BIS Billing 3.0, May 2026 release, EN 16931 model bound to UBL
Severity note: fatal, from the Flag column of the Peppol BIS Billing 3.0 UBL rules index retrieved 2026-10-18.
The Sum of Invoice line net amount (BT-106) may have at most 2 decimals. The statement says "allowed maximum number of decimals" and "is 2", and it ends with a period. It does not say shall. The context is cac:LegalMonetaryTotal. This is a decimal limit, not the BR-CO-10 sum. The published test reads cbc:LineExtensionAmount and writes <=2 with no space before <=. It does not call exists.
Send the Sum of Invoice line net amount (BT-106) with at most 2 digits after the decimal point.
Illustration of the condition in the official statement. Not an example published by the source.
Fails the stated condition. The sum of invoice line net amount has 3 digits after the decimal point.
Passes the stated condition. That sum has 2 digits after the decimal point.
