Hi,Sridhar
    In fact , It doesn't matter you employ model node or value node .if you created mode node ,you are able to <b>bind</b> it to BAPI directly , this means you don't have to care how the data tranfer from BAPI to costom controller context due to BIND system provided by Web Dynpro Frame.  how ever , if you used value node ,you have to get data from BAPI to context node manually . This is also the case between custom controller and view controller.
           we use mode mode.  in your case :
        <b>1.</b> Creat a mode node with two attribute name and ID within customer controller, then binding this node to your BAPI node corresponding  your name and ID field (Don't have to bind the entire input node )
        <b>2.</b> Creat a method in your customer controller like this :
        public void callRFC( )
    //@@begin callRFC()
     Z_Allcountry_Input input(your excutable class) ;
     input = new  Z_Allcountry_Input();
     try{
            input.execute();
          } catch(WDDynamicRFCExecuteException ce) {
                      msgMgr.reportException(ce.getMessage(), false);
     wdContext.nodeOutputlist().bind(input.getOutput().getZkeyandname());
    //Zkeyandname is your class corresponding name and id      
    //@@end
<b>3.</b> Creat mode node which have same structure as customer controller in view controller ,<b>mapping</b> it to customer comtroller .
<b>4.</b> in your WDinit method in view controller:
         IWDAttributeInfo attributeInfo =
          wdContext.getNodeInfo().getAttribute(IPrivateNationalityView.IContextElement.ID);
          ISimpleTypeModifiable countryType = attributeInfo.getModifiableSimpleType();
          ISeachhelpdataElement  element;
          wdThis.wdGetSeachhelpfornationlityController().<b>callRFC();</b>
          IModifiableSimpleValueSet valueSet =
          countryType.getSVServices().getModifiableSimpleValueSet();
          countryType.setFieldLabel("NAME");
          for ( int i = 0 ; i < wdThis.wdGetContext().nodeSeachhelpdata().size() ;  i++ )
               element = (ISeachhelpdataElement)wdThis.wdGetContext().nodeSeachhelpdata().getElementAt(i);
               valueSet.put(element.getID(),element.getNAME());
