PEPPOL-EN16931-R043-1

In CII the charge indicator of an allowance or charge at document or line level must be exactly true or false. This rule checks the ram:SpecifiedTradeAllowanceCharge group.

Severity: Error
Applies to: CII
Rule set: v2026-01-31

Official rule text

Allowance/charge ChargeIndicator value MUST equal 'true' or 'false'

Why does PEPPOL-EN16931-R043-1 happen?

In CII the value sits one level deeper than in UBL, inside ram:ChargeIndicator/udt:Indicator. Mappings ported from UBL write it straight into ram:ChargeIndicator, or carry over the database's 1 and 0.

How do you fix PEPPOL-EN16931-R043-1?

Write true or false in lower case into ram:ChargeIndicator/udt:Indicator inside ram:SpecifiedTradeAllowanceCharge. The same requirement applies to price-level allowances in a different place — see R043-2.
