Try with below code...

PARAMETERS: p_chb AS CHECKBOX USER-COMMAND chb,
            p_file TYPE localfile.

DATA: i_filetable TYPE filetable,
      wa_filetable TYPE file_table,
      g_rc TYPE i.

AT SELECTION-SCREEN OUTPUT.

  LOOP AT SCREEN.
    IF screen-name CP '*P_FILE*'.
      IF p_chb IS INITIAL.
        screen-active = 0.
      ELSE.
        screen-active = 1.
      ENDIF.
      MODIFY SCREEN.
    ENDIF.
  ENDLOOP.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_file.

  CALL METHOD cl_gui_frontend_services=>file_open_dialog
    EXPORTING
      window_title            = 'Save As...'
    CHANGING
      file_table              = i_filetable
      rc                      = g_rc
    EXCEPTIONS
      file_open_dialog_failed = 1
      cntl_error              = 2
      error_no_gui            = 3
      not_supported_by_gui    = 4
      OTHERS                  = 5.
  IF sy-subrc EQ 0.
*** Display Local Directories for file selection
    READ TABLE i_filetable INTO wa_filetable INDEX 1.
    MOVE wa_filetable-filename TO p_file.
  ENDIF.

Kind Regards
