PEPPOL-EN16931-R043-1: ChargeIndicator of an allowance or charge is not true or false (CII)

What does this mean?

Allowance/charge ChargeIndicator value MUST equal 'true' or 'false': the indicator whether an entry is a charge or an allowance (ram:ChargeIndicator/udt:Indicator) must have exactly the value true or false. The value is different.
The rule originates from Peppol BIS Billing 3.0 and is applied in the XRechnung validation for CII, to ram:SpecifiedTradeAllowanceCharge, i.e. document level allowances and charges (BG-20, BG-21) and line level allowances and charges (BG-27, BG-28). For discounts in the item price see PEPPOL-EN16931-R043-2.

Typical causes

The value was given as 1 or 0; XML Schema allows this, this rule does not.
Upper case (TRUE, False) or an empty element.

How to fix the error

State udt:Indicator as true for a charge or false for an allowance, in lower case.
Generate and validate the invoice again.

Example

Wrong

<ram:SpecifiedTradeAllowanceCharge>
  <ram:ChargeIndicator>
    <udt:Indicator>0</udt:Indicator>
  </ram:ChargeIndicator>
  <ram:ActualAmount>10.00</ram:ActualAmount>
  ...
</ram:SpecifiedTradeAllowanceCharge>

Correct

<ram:SpecifiedTradeAllowanceCharge>
  <ram:ChargeIndicator>
    <udt:Indicator>false</udt:Indicator>
  </ram:ChargeIndicator>
  <ram:ActualAmount>10.00</ram:ActualAmount>
  ...
</ram:SpecifiedTradeAllowanceCharge>
