ALV Grid is not Displaying after executing?

Question

Hi Guys,
             I am using ALV grid in my program with OO Concepts.I was not able to see the final o/p after entering the data into the selection Screen.Can anybody tell me what's the reason.I am sending u the code.
     Call Method grid1->set_table_for_first_display
            Exporting I_Structure_name = 'T_FINAL_OUT'
             Changing it_outtab = i_final_out1[]
                      it_fieldcatalog = I_FCAT
             Exceptions
                      Invalid_parameter_combination = 1
                      program_error                 = 2
                      too_many_lines                = 3
                      Others                        = 4.
             If sy-subrc <> 0.
             ENDIF.
Please respond to this mail

  My only doubt is regarding Container does i need to crerate a conatiner .I created a custome control also but same problem
Data : grid1 type ref to cl_gui_alv_grid,
       g_custom_container type ref to cl_gui_custom_container,

Structure  for layout
      i_layout_s   TYPE  lvc_s_layo,
      i_lvccat TYPE lvc_t_fcat,
INITIALIZATION of Fields
Initialization.
  v_repid = sy-repid.
  set screen '101'.
  MODULE STATUS_0101 output.
