 Configuration of MessagesLocate this document in the navigation structure

You can configure how Messages are displayed at view or window level of your application. To do this, add the following source code to the method WDDOINIT:

Web Dynpro Component MYCOMP 

data:
    l_api_mycomp type ref to if_wd_window_controller,
    l_wd_message_area type ref to if_wd_message_area.
 
  l_api_mycomp ?= wd_this->wd_get_api( ).
  l_wd_message_area = l_api_mycomp->get_message_area( ).
  l_wd_message_area->set_display_attributes( i_for_all_instances = ' '
                                             i_msg_lines_visible = '0'
                                             i_use_toggle_area   = '  '
                                             i_show_only_current = ' ' ).
