The allowance or charge indicator is neither “true” nor “false”
`ChargeIndicator` must be exactly `true` or `false`. This code is returned on UBL documents; in CII the same checks carry the codes `PEPPOL-EN16931-R043-1` and `PEPPOL-EN16931-R043-2`.
Only the issuer holds this value: Factlint reports it and never fabricates it. Test your invoice to find out whether it is affected.

Common searches around this code
These phrases mirror what an integrator searches for: code, syntax, rule, business field and correction.
Test your file with this error in mind
Upload the invoice involved: the report will say whether this code appears, where it appears in the document, and whether Factlint can only report it or also fix it.
To automate this check in an ERP flow, call the validation API and link every returned code to its public page.
Why this error happens
XML accepts `1` and `0` as booleans; the rule does not. The indicator decides whether the amount is added to or subtracted from the total: its value carries a sign, and a spelling the recipient could read the wrong way is not tolerated.
How to fix it
Have your generator write `true` or `false`. Factlint does not normalise this value: it governs the direction of an amount, and an automatic correction that got it wrong would turn a discount into a surcharge.
XML correction example
<cbc:ChargeIndicator>1</cbc:ChargeIndicator>
<cbc:ChargeIndicator>false</cbc:ChargeIndicator>
