Hi Swarup,
I have implemented the exact scenario, this is what you need to do.
FORM f_alv_user_comm USING i_ucomm TYPE syucomm           
                          i_rs TYPE slis_selfield.
*  Display ALV2 (This list shows the list blocked/unblocked customers)
    PERFORM f_display_alv2 CHANGING i_ucomm.
  IF i_ucomm EQ '&F03'.         " here you can use the back button code
* Return to seletion screen
    LEAVE TO SCREEN 0.
  ENDIF.
endform.
In f_display_alv2 do like this :
FORM f_display_alv2 CHANGING e_ucomm TYPE syucomm.
    CALL FUNCTION 'REUSE_ALV_LIST_DISPLAY'
      EXPORTING
        i_bypassing_buffer = c_mark
        i_callback_program = w_repid
        is_layout          = lws_layout
        it_fieldcat        = int_fieldcat2[]
        it_events          = int_events_alv2
      TABLES
        t_outtab           = int_alv2_out
      EXCEPTIONS
        program_error      = 1
        OTHERS             = 2.
    IF sy-subrc <> 0.
      MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
              WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
    ELSE.
      e_ucomm = '&F03'.                          " This will take the back button code
    ENDIF.
endform.
This is the right way to do it.
