Pass a parameter in a Web Dynpro Application

Question

Hi,
I have a Web Dynpro that Calls a RFC. This RFC needs a parameter (user ID from portal) in order to obtain Info. from the R/3 System.
I do it with based on the article which calls a bapi "BAPI_FLIGHTLIST".
The application runs OK when I type the parameter (user ID) in an "input field", it only return the information needed (method button) from R3. Now, if I want to get the parameter (user ID) automatically from the Web Dynpro ( the user who Logon into the portal) the application does not work.
I try with this code but isn't work.
wdContext.currentZrfc_Prueba_Portal_InputElement().setZusuario(userid);
How can I set the parameter (Zusuario) in my input field automatically and after I press the button (method) return my info.???
Here is the code.
The method wdDOInit
Zrfc_Prueba_Portal_Input input = new Zrfc_Prueba_Portal_Input();
wdContext.nodeZrfc_Prueba_Portal_Input().bind(input);
The method that Execute a RFC
//@@ Begin Take USer
       String userid="";
          try {
               IWDClientUser user = WDClientUser.getCurrentUser();
               userid = user.getSAPUser().getUniqueName();
          } catch (WDUMException e) {
               e.printStackTrace();
//@@ End Take USer
//@@ Begin Set the login user to Zusuario parameter
          wdContext.currentZrfc_Prueba_Portal_InputElement().setZusuario(userid);
//@@ End Set the login user to Zusuario parameter
          //@@ Begin Method that execute the RFC
          try {
                        wdContext.currentZrfc_Prueba_Portal_InputElement().modelObject().execute();
               wdContext.nodeOutput().invalidate();
               wdComponentAPI.getMessageManager().reportSuccess(
                         "Execute whit the user: "
                                   + wdContext
                                             .currentZrfc_Prueba_Portal_InputElement()
                                             .getZusuario().toString());
          } catch (Exception e) {
               e.printStackTrace();
               wdComponentAPI.getMessageManager().reportException("Caution " + e);
          //@@ End Method that execute the RFC
Any help will be rewarded.

Hi Bala Duvvuri,
I taste your code but isn't work.
This the method wdDoInit
public void wdDoInit()
    //@@begin wdDoInit()
       Zrfc_Prueba_Portal_Input input = new Zrfc_Prueba_Portal_Input();
       wdContext.nodeZrfc_Prueba_Portal_Input().bind(input);
    //@@end
This the method ExecuteRFC
public void ExecuteRFC( )  {
    //@@begin ExecuteRFC()
         Zrfc_Prueba_Portal_Input input = new Zrfc_Prueba_Portal_Input();
       wdContext.nodeZrfc_Prueba_Portal_Input().bind(input);
       //@@ Begin Take USer
       String userid="";
       try {
               IWDClientUser user = WDClientUser.getCurrentUser();
               userid = user.getSAPUser().getUniqueName();
          } catch (WDUMException e) {
               e.printStackTrace();
           //@@ End Take USer
          //@@ Begin Set the login user to Zusuario parameter
          input.setZusuario(userid);          
          //@@ End Set the login user to Zusuario parameter
          //@@ Begin Method that execute the RFC
          try {
               wdContext.currentZrfc_Prueba_Portal_InputElement().modelObject().execute();
               wdContext.nodeOutput().invalidate();
               wdComponentAPI.getMessageManager().reportSuccess(
                  "Execute whit the user: "
                    + wdContext
                            .currentZrfc_Prueba_Portal_InputElement()
                         .getZusuario().toString());
          } catch (Throwable e) {
               e.printStackTrace();
               wdComponentAPI.getMessageManager().reportException("Caution " + e);
          //@@ End Method that execute the RFC
    //@@end
