Multiline mapping

Question

Hi,
There are many invoices present in the incoming message.
I have to make a single Bapi call for each invoice.
For this purpose in the BPM I need to map the message to a multiline container, so that in the next block I can loop each line of this multiline container to the required Bapi.
Now, I have this problem in the mapping of the received message into a multiline container. The transformation step in BPM is not giving any result in the output.
For your reference, I am giving below the input and result of the mapping (into a multiline container below) I need
1. Input:
<ns1:MT_scan_invoice xmlns:ns1="urn:customers:invoice">
<Invoice>
</Invoice>
<Invoice>
</Invoice>
</ns1:MT_scan_invoice>
2. Result needed:
<ns1:MT_scan_invoice xmlns:ns1="urn:customers:invoice">
<Invoice>
</Invoice>
</ns1:MT_scan_invoice>
<ns1:MT_scan_invoice xmlns:ns1="urn:customers:invoice">
<Invoice>
</Invoice>
</ns1:MT_scan_invoice>
I have done mapping where, I have mapped the "Invoice" node (which is unbounded) to the target node of "MT_scan_invoice ".
I am using the same message in the source and target side of mapping.
In the 'Messages' tab of message mapping and in the 'Design' tab of interface mapping, I have changed the occurrence of the target message to '0..unbounded'. Also in the BPM the target container is multiline.
The interface and message mapping in stand-alone mode is giving successful outputs. (as desired)
Still the transformation step in Runtime is giving an empty output. Did I miss something in the mapping?
Kindly help. For the last 2 weeks, I am stuck with this issue.
Also kindly suggest alternate methods to generate a multiline container.
Thanks,
John

Hi Mario,
I tested the sample BPM by creating one receiver and one interface determination.
But the 'MultipleFlightBookingCoordination' also is not giving any output in the first mapping.
I used the sample payload given below.
<?xml version="1.0" encoding="UTF-8"?>
<ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
   <ns0:Message1>
      <ns1:MultipleBookingOrderRequest xmlns:ns1="http://sap.com/xi/XI/Demo/Agency">
         <AgencyID>1</AgencyID>
         <OrderNumber>2</OrderNumber>
         <FlightClass>2</FlightClass>
         <BookingOrderList>
            <ItemNumber>3</ItemNumber>
            <FlightID>
               <AirlineID>4</AirlineID>
               <ConnectionID>5</ConnectionID>
               <FlightDate>6</FlightDate>
            </FlightID>
            <PassengerData>
               <Surname>6</Surname>
               <FirstName>7</FirstName>
               <Birthdate>8</Birthdate>
            </PassengerData>
         </BookingOrderList>
         <BookingOrderList>
            <ItemNumber>3</ItemNumber>
            <FlightID>
               <AirlineID>4</AirlineID>
               <ConnectionID>5</ConnectionID>
               <FlightDate>6</FlightDate>
            </FlightID>
            <PassengerData>
               <Surname>6</Surname>
               <FirstName>7</FirstName>
               <Birthdate>8</Birthdate>
            </PassengerData>
         </BookingOrderList>
      </ns1:MultipleBookingOrderRequest>
   </ns0:Message1>
</ns0:Messages>
The first transformation mapping is supposed to split the message.
But this is not happening. In the trace of BPM, the out message is empty.
Kindly do a simple test and help to see what is wrong.
Even after raising OSS call, this issue is pending.
Thanks,
John
