Outbound EDI Batching

Hi

I have an XML file that has the following structure

<EDI Header></EDI Header>

<ScheduleInfo>

  <ScheduleHeaderInfo><!–1 or more repetitions:–>

<Schedule Header>

<TransportTypeInfo><!–1 or more repetitions:–>

<TransportDetails>

<CallDetailsInfo><!–1 or more repetitions:–>

<CallDetails>

</CallDetails>

</CallDetailsInfo>

</TransportDetails>

</TransportTypeInfo>

    </ScheduleHeader>

<Schedule Header>

  .

  .

 .

     </ScheduleHeader>

  <Schedule Header>

  .

.

.

<\ScheduleHeaderInfo>

</ScheduleInfo>

My aim is to generate multiple transactions (i.e UNH – UNT, UNH – UNT,..) in a single EDIFACT. I have successfully extracted the individual transactions based on the number of schedule header exists in the file (using Looping in Orchestration). Now i have to generate a single UN EDIFACT with all this extracted Individual transactions. Can anyone guide me how to achieve this?
