VF02 - CHANGE BILLING DOCUMENT

Question

Hi All,
I had a requirement, In the Transaction VF02(CHANGE BILLING DOCUMENT) after the SD billing document is created and when the option 'ReleaseToAccounting' is selected an OutBound Idoc should be created for the FI InvoiceHi All,
My question is how to create a custom idoc for FI invoices via a user exit and these idocs will be routed (via RFC) to a JAVA server/processor. Pls suggest how can i acheive this.
Is there any user exit for acheiveing this or can we proceed further without user exit also.
If so how to acheive this.
Thanks & Regards,
Anil.

Hi Anil,
SAP Java Connector - Example: Simple RFC call
Scenario:
We will call the RFC function module ZNAS_HIE1_GET_MEMBER_FARM.that returns members that have owned a farm. Input to the function is a farm number, and output is a table of members that have owned the farm and Owner number (Sequence number of owners).
Class testJCO is excuted and calls class GetMemberFarm method GetMemberFarmFromSap. Input parameters to GetMemberFarm are Farm and Owner number.
GetMemberFarmFromSap executes RFC ZNAS_HIE1_GET_MEMBER_FARM, that returns a table of members that have owned the farm from the input parameters.
GetMemberFarmFromSap loops through the table and finds the member where ZZCHCODE (Owner numer), is equal owner number from the input-parameters. and returns the member.
Code
Class testJCO
public class testJco
     public static void main(String[] args)
          GetMemberFarm testGetMemberFarm = new GetMemberFarm();
          String memberFarm= testGetMemberFarm.GetMemberFarmFromSap("0111020155","02");
          System.out.println("Memberfarm: " + memberFarm);
Class GetMemberFram
import com.sap.mw.jco.*;  //The JCO
public class GetMemberFarm {
  public String GetMemberFarmFromSap(String farm, String OwnerNumber)   
  {  String zzmemb ="";
        String memberFarm = "";
     JCO.Repository mRepository;

                                        "53.205.22.71", //Host
                                        "03");           //System
         mConnection.connect();
         System.out.println("Connection OK");
       catch (Exception ex)
            System.out.println(ex);
      // Create function and parameters
      try
        //Create repository
        mRepository = new JCO.Repository( "GetMember", mConnection );
        //Get a function template from the repository
        IFunctionTemplate ftemplate = mRepository.getFunctionTemplate("ZNAS_HIE1_GET_MEMBER_FARM");
        //Create function

        System.out.println("Function created");
        //Set import parameter
        JCO.Field zzfarm = myFunction.getImportParameterList().getField("ZZFARM");
        zzfarm.setValue(farm);
        System.out.println("Parameters ok");
     catch (Exception ex)       
          System.out.println(ex);
     // Execute function
     try
          mConnection.execute(myFunction);
        System.out.println("RFC Call OK");          
     catch (Exception ex)

          for (int i = 0; i < gt_HIERARCHY.getNumRows(); i++)
          {   gt_HIERARCHY.setRow(i);
              String zzchcode = gt_HIERARCHY.getString("ZZCHCODE");
              if (zzchcode.equals(OwnerNumber))                        
                   zzmemb = gt_HIERARCHY.getString("ZZMEMB");                   
     catch (Exception ex)      
      {  System.out.println(ex);           
     // Disconnect from SAP
     try
         mConnection.disconnect();  
         System.out.println("Disconnected from SAP");
      catch (Exception ex)
