What does this mean?

For a document level allowance (BG-20) with VAT category (BT-95) L (IGIC, Canary Islands general indirect tax) the document level allowance VAT rate (BT-96) must be stated. The rate is missing or too low.
The rule text requires "0 (zero) or greater than zero"; the official CII check, however, requires a rate greater than 0, the UBL check a rate of 0 or more.

Typical causes

The rate was not stated.
CII: rate 0 was stated.

How to fix the error

State the rate (greater than zero for CII) for every document level allowance of category L.
If the rate does not match the category, correct the category and adjust the VAT breakdown (BG-23).
CII: ram:SpecifiedTradeAllowanceCharge (ChargeIndicator false)/ram:CategoryTradeTax/ram:RateApplicablePercent, UBL: cac:AllowanceCharge (cbc:ChargeIndicator false)/cac:TaxCategory/cbc:Percent.

In E-Rechnungsfreund

In the invoice form ("Experte" view), section "Zu-/Abschläge auf Dokumentenebene (BG-20/BG-21)" (document level allowances and charges), for every entry of type "Abschlag (BG-20)" (allowance) with "St-Kat." (VAT category) L fill in the field "St-Satz %" (VAT rate). An empty field is not written to the XML for the allowance/charge.

  <ram:CategoryTradeTax>
    <ram:TypeCode>VAT</ram:TypeCode>
    <ram:CategoryCode>L</ram:CategoryCode>
  </ram:CategoryTradeTax>
