Generate new IDOC if any Header field value changed

Hi Experts,

My scenario is File to IDOC. I will get a CSV file with header and line item data. I have to compare all values one by one in a Field, If any value changed, I have to generate new IDOC at target side with the corresponding Header data and line item data. In the same way I have to compare values for all fields in header.

My input XML will be like this.

<Record>

   <Header>

        <Field1>

        <Field2>

        <Field3>

        <Field4>

  </Header>

  <LineItem>

         <Field1>

         <Field2>

         <Field3>

         <Field4>

   </LineItem>

</Record>

Thanks in advance,

Kishore.
