Problem after multiselection on table

Question

hi
    i have a  table  IT_car_data  where i have to perform 
    multiselection in the table , and iam populated the 
     data in to the table from the itemlistbox , then i need
      to perform multiselection on the table and send it to a structure called It_Car , and add the Structure It_car to the
RFC.
  for(int i=0;i<n;i++)
              if(wdContext.nodeIt_Car_Data().isMultiSelected(i) || leadSelection==i )
String make=wdContext.nodeIt_Car_Data().getIt_Car_DataElementAt(j).getP_Make();
here below  Zlgs_Car_Data is class for IT_Car Structure Zlgs_Car_Data carData=new Zlgs_Car_Data();
                          carData.setP_Make(make);
wdContext.currentZlgf005_Outfit_Match_Mm_InputElement().modelObject().addIt_Car(carData);
then calling the RFC 
what is  happening is  when i perform multi select and click on the button for example: 1 and 2  row , i able to send it to
IT_Car, but for the second time when i deselect 1 and 2  and
select 3 and 4 rows  and send it to IT_Car, iam able to
see all 1,2,3,4 row in the IT_Car , but i need the only latest one that 3 and 4 row in the It_car ,
after i perform 1,2 row multiselection onthe table  and call the
RFC  , i need to invalidate the node so as to clear the IT_car
but iam not able to .
can any one help me?

hi
   thanks for the response
   i have what u have send , but data is not gettign invalidated.
   for(int i=0;i<n;i++)
              if(wdContext.nodeIt_Car_Data().isMultiSelected(i) || leadSelection==i )
                  wdContext.nodeIt_Car_Data().setLeadSelection(i);
          String pMake =wdContext.nodeIt_Car_Data().getIt_Car_DataElementAt(i).getP_Make();
                       String pModel=wdContext.nodeIt_Car_Data().getIt_Car_DataElementAt(i).getP_Model();
  Zlgs_Car_Data carData = new Zlgs_Car_Data();
                                                      carData.setP_Make(pMake);
                              carData.setP_Model(pModel);
wdContext.currentZlgf005_Outfit_Match_Mm_InputElement().modelObject().addIt_Car(carData);
the above code is for the first Table It_car_data , where i am performing multi match on this table It_car_data .
next step
for(int j=0;j<n1;j++)
if(wdContext.nodeIt_Carv_Data().isMultiSelected(j) || carvLeadSelection==j)            
                    wdContext.nodeIt_Carv_Data().setLeadSelection(j);
                         String make=wdContext.nodeIt_Carv_Data().getIt_Carv_DataElementAt(j).getP_Make();
                    String model=wdContext.nodeIt_Carv_Data().getIt_Carv_DataElementAt(j).getP_Model();
                    String range=wdContext.nodeIt_Carv_Data().getIt_Carv_DataElementAt(j).getP_Range();
Zlgs_Carv_Data carvData=new Zlgs_Carv_Data();
                              carvData.setP_Make(make);
                           carvData.setP_Model(model);
                           carvData.setP_Range(range);
                           wdContext.currentZlgf005_Outfit_Match_Mm_InputElement().modelObject().addIt_Carv(carvData);
in the above  iam performing single selection on  the
table IT_carv_data , i have written ismultiselected()  because
i can perform single selection or multiselection.
but for my requirement i need only single selection  as of now
, multi selection will come is the later stage , so i have used
ismultiselected ,
after the above two loops i have called the RFC
       wdthis.wdGetRFC.executeRFC();
     after calling the RFC i have written
wdcontext.currentRFC.modelobject.removeIt_Car(carData);
carData is the strucute IT_Car 's  class Zlgs_Car_Data instance .
i have declared  inthe //@@begin others
      Zlgs_Carv_Data carvData=new Zlgs_Carv_Data();
        Zlgs_Car_Data carData = new Zlgs_Car_Data();
//@end
but the problem i am not able to remove the  data .
can any plz help me .?  
valuable answer point will be rewared
