Set the default field value to transaction code field, when calling from WD

Question

Hi all,
Can we pass the value in a input field of a standard transaction calling from WD application. Suppose we are calling a transaction VA03 in an external window, then how will be pass the value in the VBAK_VBELN screen field.
Is there any way to pass the value to this transaction field. I have also tried out to set the parameter ID 'AUN' for VA03 transaction VBELN field. But it did not work for me.
Is there any way to set the default field value to transaction code field, when calling from WD?
Please suggest, if anyone have any idea.
Thanks

Hi,
I am using the below code to open a standard transaction. It will help you to explain my point more easily.
DATA: url TYPE string,
          host TYPE string,
          port TYPE string.
*Call below method to get host and port
  cl_http_server=>if_http_server~get_location(
     IMPORTING host = host
            port = port ).
*create URL
  CONCATENATE 'http'
  '://' host ':' port
  '/sap/bc/gui/sap/its/webgui/?sap-client=&~transaction=' 'VA03'
   INTO url.
*get the window manager as we are opening t code in external window.
  DATA lo_window_manager TYPE REF TO if_wd_window_manager.
  DATA lo_api_component TYPE REF TO if_wd_component.
  DATA lo_window TYPE REF TO if_wd_window.
  lo_api_component = wd_comp_controller->wd_get_api( ).
  lo_window_manager = lo_api_component->get_window_manager( ).
call the url which we created above
  lo_window_manager->create_external_window(
  EXPORTING
  url = url
  RECEIVING
  window = lo_window ).
  lo_window->open( ).
Note*
One more query I want to add to this thread, that is there any possibility to call a custom transaction as well?
