Describe the bug

XML Values are wrong. Here is an example:

In the XML I got:

      <ram:SpecifiedLineTradeSettlement>
        <ram:ApplicableTradeTax>
          <ram:TypeCode>VAT</ram:TypeCode>
          <ram:CategoryCode>S</ram:CategoryCode>
          <ram:RateApplicablePercent>19.00</ram:RateApplicablePercent>
        </ram:ApplicableTradeTax>
        <ram:SpecifiedTradeSettlementLineMonetarySummation>
          <ram:LineTotalAmount>1113.69</ram:LineTotalAmount>
        </ram:SpecifiedTradeSettlementLineMonetarySummation>
      </ram:SpecifiedLineTradeSettlement>

The tax is correct but the LineTotalAmount is 1113.69 I dont know where this number is coming from.
Then

      <ram:ApplicableTradeTax>
        <ram:CalculatedAmount>211.60</ram:CalculatedAmount>
        <ram:TypeCode>VAT</ram:TypeCode>
        <ram:BasisAmount>1113.69</ram:BasisAmount>
        <ram:CategoryCode>S</ram:CategoryCode>
        <ram:RateApplicablePercent>19.00</ram:RateApplicablePercent>
      </ram:ApplicableTradeTax>

Also here the 1113.69 is wrong and because of that the tax here is 211.66 instead of the 222.74 from the PDF invoice.
The last Part

      <ram:SpecifiedTradeSettlementHeaderMonetarySummation>
        <ram:LineTotalAmount>1172.30</ram:LineTotalAmount>
        <ram:ChargeTotalAmount>0.00</ram:ChargeTotalAmount>
        <ram:AllowanceTotalAmount>0.00</ram:AllowanceTotalAmount>
        <ram:TaxBasisTotalAmount>1172.30</ram:TaxBasisTotalAmount>
        <ram:TaxTotalAmount currencyID="EUR">222.74</ram:TaxTotalAmount>
        <ram:RoundingAmount>0.00</ram:RoundingAmount>
        <ram:GrandTotalAmount>1395.04</ram:GrandTotalAmount>
        <ram:TotalPrepaidAmount>1395.04</ram:TotalPrepaidAmount>
        <ram:DuePayableAmount>0.00</ram:DuePayableAmount>
      </ram:SpecifiedTradeSettlementHeaderMonetarySummation>

Here is everything correct.

Steps To Reproduce

1.Under Settings --> Product Settings --> enable Productdiscount
2. Create a Inovice with an productdiscount
3. Send Invoice with a line discount with XML (xInvoice 3.0 in my test)

Expected Behavior

The discount must be used in the calculation for the XML. Otherwise the taxes and line values are wrong.

@LarsK1 are we factoring in discounts with the calculations?

[LarsK1]

@turbo124 yes we we're, but in x invoice 3.0 the schema changed. The fix is already available in #9523

@support-tt please check, once the next release is ready.
