What does this mean?

In a VAT breakdown (BG-23) with category K (Intra-community supply, VAT exempt) the VAT category taxable amount (BT-116) must equal the sum of the invoice line net amounts (BT-131) minus the document level allowances (BT-92) plus the document level charges (BT-99) with category K. The amount deviates from it.
The sums are taken over all entries of category K, regardless of the rate. In CII the official check tolerates a deviation of less than one currency unit, in UBL the amount must match exactly.

Typical causes

The taxable amount was entered manually or not recalculated after the lines were changed.
A document level allowance or charge of category K was not taken into account or with the wrong sign.
The lines of category K are split over several breakdowns (e.g. with and without rate); each contains only part of the sum (see also BR-IC-01).

How to fix the error

Recalculate BT-116 per category: sum of BT-131 of the lines + sum of BT-99 of the charges − sum of BT-92 of the allowances, only entries with category K, rounded to two decimals.
CII: ram:ApplicableHeaderTradeSettlement/ram:ApplicableTradeTax/ram:BasisAmount, UBL: cac:TaxTotal/cac:TaxSubtotal/cbc:TaxableAmount.
Generate and validate the invoice again.

In E-Rechnungsfreund

In the invoice form, the taxable amount per VAT category and rate (BT-116) is calculated from the invoice lines and the allowances and charges when the XML is generated, and rounded to two decimals; the value in the field "Nettobetrag (BT-116)" in section "Steueraufstellung (BG-23)" (VAT breakdown) is not used for this. Enter amounts of allowances/charges with no more than two decimals.
Enter the same rate 0 for all lines and allowances/charges of category K (fields "Steuersatz % (BT-152)" and "St-Satz %", "Experte" view) so that only one breakdown results.

Example

Wrong

<!-- Lines K: 600.00 + 400.00, allowance K: 50.00 -->
<ram:ApplicableTradeTax>
  <ram:CalculatedAmount>0.00</ram:CalculatedAmount>
  <ram:TypeCode>VAT</ram:TypeCode>
  <ram:BasisAmount>1000.00</ram:BasisAmount>

  <ram:ExemptionReasonCode>VATEX-EU-IC</ram:ExemptionReasonCode>
  <ram:RateApplicablePercent>0</ram:RateApplicablePercent>
</ram:ApplicableTradeTax>

Correct

<!-- Lines K: 600.00 + 400.00, allowance K: 50.00 -->
<ram:ApplicableTradeTax>
  <ram:CalculatedAmount>0.00</ram:CalculatedAmount>
  <ram:TypeCode>VAT</ram:TypeCode>
  <ram:BasisAmount>950.00</ram:BasisAmount>
  <ram:CategoryCode>K</ram:CategoryCode>
