Advanced mapping from IDOC to SOAP with reversed 3 level context change

Question

Hi everyone.
I am having a though time mapping the HRMD_A01 IDOC into a SOAP message. The reason is that the reciever expects an xml structure where the root node is cost center instead of employee which is the case in the IDOC.
Mapping from:
IDOC (1..1)
   E1PLOGI (1..unb)
     SEGMENT (String)
     OBJID (String)
     E1PITYP (1..unb)
       E1P0001 (1..unb)
         SEGMENT (String)
         KOSTL (String)
To this structure:
List (1..1)
  CostCenters (1..unb)
    KOSTL (String)   ----> Mapped against KOSTL above
    Employees (1..unb)
      OBJID (String)   ----> Mapped against OBJID above  
I expect several occurances of E1PLOGI which states multiple employees sent in the IDOC. I also expect several occurences of E1P0001 containing cost centers.
My conclusion is that I need an advanced mapping and I have created one which collects all KOSTL for the IDOC context, deletes duplicates, and creates the CostCenters segment. This is now working. But my problem is that I can't create the employees segment in the right place. They are only created once under the first CostCenters node.
Here's the java-code for mapping between KOSTL and CostCenters/KOSTL:
public void costCenters(String[] var1, ResultList result, Container container) throws StreamTransformationException{
  Set set = new HashSet(Arrays.asList(var1));
  String[] array2 = (String[])(set.toArray(new String[set.size()]));
  Arrays.sort(array2);
  for (int i = 0; i < array2.length; i++) {
    result.addValue(array2<i>);
Any ideas on how to proceed?
Best Regards

Hi,
  Do the mapping like below.
  UDF should be select as context.
List (1..1)
  CostCenters (1..unb)
    KOSTL (String)   ----> Mapped against KOSTL above
    Employees (1..unb)
      OBJID (String)   ----> Mapped against OBJID above
Mapping:
KOSTL(RightSelectChange the context to E1PITYP)--UDF--Removecontext--CostCenters
KOSTL(RightSelectChange the context to E1PITYP)--UDF--SplitbyValue(Each Value)--KOSTL
constant---Employees
OBJID----------------------------------------------Use One As Many---SplitByValue (EachValue)----------OBJID
KOSTL(RightSelectChange the context to E1PITYP)--UDF---
KOSTL(RightSelectChange the context to E1PITYP)--UDF---
