IDOC to XML Mapping

Question

Hi,
We have a requirement to sum up the total amount by credit card
i.e.. there will be multiple credit cards, and for each credit card there will be multiple entries,
so i need to sum up AMOUNT for each CREDITCARD and map it to TOTALAMOUNT in Destination.
Please tell me the best way to do this?
Thanks,
Sarva.

Hi Sarva,
You can use Cumulative Sum functoid with second parameter as "1".
I have created one sample xsd from the sample u provided. Used below instance for testing:
<ns0:ZPAYMENT_EXTRACT xmlns:ns0="http://sample_dynamicXSLT.input_idocSchema">
  <IDOC>
    <BEGIN>BEGIN_0</BEGIN>
    <EDI_DC40>
      <field1>field1_0</field1>
      <field2>field2_0</field2>
    </EDI_DC40>
    <Z1PAYHDR>
      <SEGMENT>Girish</SEGMENT>
      <ACCOUNT>111</ACCOUNT>
      <XMIT_DATE>XMIT_DATE_0</XMIT_DATE>
      <Z1PAYDTL>
        <PAYMENT_DATE>PAYMENT_DATE_0</PAYMENT_DATE>
        <AMOUNT>100</AMOUNT>
        <CREDIT_CARD>ABC</CREDIT_CARD>
      </Z1PAYDTL>
 <Z1PAYDTL>
        <PAYMENT_DATE>PAYMENT_DATE_0</PAYMENT_DATE>
        <AMOUNT>200</AMOUNT>
        <CREDIT_CARD>PQR</CREDIT_CARD>
      </Z1PAYDTL>
 <Z1PAYDTL>
        <PAYMENT_DATE>PAYMENT_DATE_0</PAYMENT_DATE>
        <AMOUNT>300</AMOUNT>
        <CREDIT_CARD>XYZ</CREDIT_CARD>
      </Z1PAYDTL>
    </Z1PAYHDR>
<Z1PAYHDR>
      <SEGMENT>Naveen</SEGMENT>
      <ACCOUNT>222</ACCOUNT>
      <XMIT_DATE>XMIT_DATE_0</XMIT_DATE>
      <Z1PAYDTL>
        <PAYMENT_DATE>PAYMENT_DATE_0</PAYMENT_DATE>
        <AMOUNT>40</AMOUNT>
        <CREDIT_CARD>ABC</CREDIT_CARD>
      </Z1PAYDTL>
 <Z1PAYDTL>
        <PAYMENT_DATE>PAYMENT_DATE_0</PAYMENT_DATE>
        <AMOUNT>80</AMOUNT>
        <CREDIT_CARD>PQR</CREDIT_CARD>
      </Z1PAYDTL>
    </Z1PAYHDR>
  </IDOC>
</ns0:ZPAYMENT_EXTRACT>
Got the output as:
<ns0:ZPAYMENT_OUT xmlns:ns0="http://sample_dynamicXSLT.output_idocSchema">
<CUSTOMER>
<SEGMENT>Girish</SEGMENT>
<ACCOUNT>111</ACCOUNT>
<TOTALAMOUNT>600</TOTALAMOUNT>
</CUSTOMER>
<CUSTOMER>
<SEGMENT>Naveen</SEGMENT>
<ACCOUNT>222</ACCOUNT>
<TOTALAMOUNT>120</TOTALAMOUNT>
</CUSTOMER>
</ns0:ZPAYMENT_OUT>
