    How are you invoking the popup window.

    where you have written the code to create it. and open it.

    and the scenario that you are saying is quite strange it should behave in teh same manner on both the system.

    you need to check it again.

    this error will come only when you are trying to open a new popup with same name again.

    • So it may be because of browser only.

      but here on my system i am using IE8 and all the applciations are running properly.

      i even tried your scenario.

      wt can be a wrokaround is put the code of creating window in the wddoinit and

      just write the code for opening the window in the onselect

      for this create an attribute of type if_wd_window and set its value after creatign it in wddoinit

      and get its value in the onselect and open it.

      and also you can try one small workaround.

      lo_api_component = wd_comp_controller->wd_get_api( ).
      lo_window_manager = lo_api_component->get_window_manager( ).
      lo_window = lo_window_manager->create_window(
      window_name = 'POPUP_WINDOW'
      title = 'Forecasting'
      * close_in_any_case = abap_true
      message_display_mode = if_wd_window=>co_msg_display_mode_selected
      close_button = abap_true
      * button_kind = if_wd_window=>co_buttons_ok
      button_kind = if_wd_window=>CO_BUTTONS_OKCANCEL
      message_type = if_wd_window=>co_msg_type_none
      default_button = if_wd_window=>co_button_ok
      lo_window->close( ).       "<<<--------- add this line and try
      lo_window->open( ).

    Are you trying to open the other component as a Popup here...I this case you will get the error.

    Ie. When you have declared other component as component usage and trying to open this component as a popup, Is this the case?
