Hi Suresh,
Please follow on the lines of below code snippets..
For your Pop Up
  DATA: lo_cmp_api TYPE REF TO if_wd_component,
        lo_window_manager TYPE REF TO if_wd_window_manager,
        lo_popup TYPE REF TO if_wd_window,
        lv_text TYPE string_table,
        lo_api TYPE REF TO if_wd_view_controller,
        lv_string TYPE string_table,
        l_string TYPE string,
        l_title type string.
*display confirmation window
  lo_cmp_api = wd_comp_controller->wd_get_api( ).
  lo_window_manager = lo_cmp_api->get_window_manager( ).
  lo_popup = lo_window_manager->create_popup_to_confirm(
               text = lv_string
               button_kind = if_wd_window=>co_buttons_yesno
               window_title = l_title
               close_button = abap_false
               message_type = if_wd_window=>co_msg_type_warning
               window_position = if_wd_window=>co_center ).
  lo_api = wd_this->wd_get_api( ).
  lo_popup->subscribe_to_button_event(
             button   = if_wd_window=>co_button_yes
             action_name = 'NO'
             action_view = lo_api
             is_default_button = abap_false ).
  lo_popup->subscribe_to_button_event(
             button   = if_wd_window=>co_button_no
             action_name = 'CANC'
             action_view = lo_api
             is_default_button = abap_true ).
  lo_popup->open( ).
Declare 'NO' and 'CANC' actions in ur view actions tab.
For checking the field
Check whether the field is empty or not in the method where you want to
check it, may be in your method to Save changes.
then
  DATA:
     lo_wd_view_controller TYPE REF TO if_wd_view_controller,
     lo_message_manager    TYPE REF TO if_wd_message_manager,
*Get the message manager controller
  lo_wd_view_controller = wd_this->wd_get_api( ).
  CALL METHOD lo_wd_view_controller->get_message_manager
    RECEIVING
      message_manager = lo_message_manager.
    IF <field> IS INITIAL.
      CALL METHOD lo_message_handler->report_error_message
        EXPORTING
          message_text = text-006.
    ENDIF.
Hope this solves your problems.
Regards,
Ismail.
