What does this mean?

The invoice line allowance amount (BT-136) may have at most two decimals. In the invoice the amount has more than two decimals.

Typical causes

The amount was taken unrounded from a calculation, e.g. from a percentage or from quantity × price.
The generating system writes amounts with a fixed number of three or four decimals, e.g. 100.0000; trailing zeros count as well.

How to fix the error

Round the amount to two decimals and write it without further digits, e.g. 100.00 instead of 100.0000.
Recalculate the invoice line net amount (BT-131) with the rounded amount.
CII: ram:SpecifiedLineTradeSettlement/ram:SpecifiedTradeAllowanceCharge/ram:ActualAmount (ram:ChargeIndicator = false), UBL: cac:InvoiceLine/cac:AllowanceCharge/cbc:Amount (cbc:ChargeIndicator = false).
Generate and validate the invoice again.

In E-Rechnungsfreund

In the invoice form, expert view ("Experte"), section "Rechnungspositionen (BG-25)" (invoice lines), tab "Zu-/Abschläge (BG-27/28)" of the line, check the field "Betrag" (amount) of the entry "Abschlag (BG-27)" (allowance). When generating the XML the application rounds the amount to two decimals. Preferably enter the amount with at most two decimals right away so that the rounded values match your records, and validate the invoice again.

Example

Wrong

<ram:SpecifiedLineTradeSettlement>
  <ram:SpecifiedTradeAllowanceCharge>
    <ram:ChargeIndicator><udt:Indicator>false</udt:Indicator></ram:ChargeIndicator>
    <ram:ActualAmount>3.7462</ram:ActualAmount>
    <ram:Reason>Rabatt</ram:Reason>
    ...
  </ram:SpecifiedTradeAllowanceCharge>
  ...
</ram:SpecifiedLineTradeSettlement>

Correct

<ram:SpecifiedLineTradeSettlement>
  <ram:SpecifiedTradeAllowanceCharge>
    <ram:ChargeIndicator><udt:Indicator>false</udt:Indicator></ram:ChargeIndicator>
    <ram:ActualAmount>3.75</ram:ActualAmount>
    <ram:Reason>Rabatt</ram:Reason>
    ...
  </ram:SpecifiedTradeAllowanceCharge>
  ...
</ram:SpecifiedLineTradeSettlement>

Frequently asked questions

Is 100.000 allowed because its value equals 100.00?

No. The check counts the characters after the decimal point, not the numeric value. 100.000 has three decimals and triggers the rule; 100, 100.0 and 100.00 are allowed.
