Add a row after Total row in ALV report

Question

Hi Experts,
I have a report is displayed by  ALV format(not use function module to display it but use Class cl_gui_custom_container),I want to add a row after the total row. for example,
Customer   amount1    amount2    amount3 
10000         1,234        1,000         2,000
10001         4,000        2,000         1,000
10002         1,300        1,000         3,000
11000         1,200        4,000         3,000
     Total:     7,734        8,000         9,000
Ratio%        31.27       32.34          36.39
the row of 'Total' is calculated by fieldcat-do_sum = 'X' But after the Total row we need a Ratio row to display the ratio. Yes we can calculate the total amout and ratio and then append it into the output itab, but we don't like this solution.We want to keep the total function in the ALV report.Any experts can poit me a direction. Thanks in advance.

Djoe,
First you need to handle the user command,in order to capture the button action. For this you need to implment a class, i  am attaching sample codes here
In top include write the following code
CLASS lcl_event_handler DEFINITION .
  PUBLIC SECTION .
    METHODS:
     handle_toolbar  FOR EVENT toolbar                   " To add new functional buttons to the ALV toolbar
                     OF        cl_gui_alv_grid
                     IMPORTING e_object,
     handle_user_command FOR EVENT user_command          " To implement user commands
                        OF cl_gui_alv_grid
                        IMPORTING e_ucomm .
  PRIVATE SECTION.
ENDCLASS.                                               " Lcl_event_handler DEFINITION
Now   <b>Class implementation</b>
CLASS lcl_event_handler IMPLEMENTATION .
  METHOD handle_toolbar.                                " Handle Toolbar
    PERFORM f9500_handle_toolbar USING e_object.
ENDMETHOD .                                            " Handle_toolbar
  METHOD handle_user_command .                          " Handle User Command
    PERFORM f9600_handle_user_command USING e_ucomm .
  ENDMETHOD.
ENDCLASS .                                              " lcl_event_handler IMPLEMENTATION
FORM f9600_handle_user_command USING p_e_ucomm TYPE sy-ucomm.
  CONSTANTS:c_newl(4) TYPE c
                      VALUE 'NEWL',               " New line
            c_copy(4) TYPE c
                      VALUE 'COPY',               " Copy
            c_corr(4) TYPE c
                      VALUE 'CORR'.               " Correction
  CASE p_e_ucomm .
    WHEN c_newl.
Create a new line
      PERFORM f9610_insert_new_line.
ENDFORM.                                          " f9600_handle_user_command
FORM f9610_insert_new_line .
*Data Declarations
  DATA: lt_rows     TYPE lvc_t_row,                 " Itab for row property
        ls_rows     TYPE lvc_s_row,                 " Work area for row
        lv_cntid    TYPE i.                         " Counter
  DATA: gv_index TYPE sy-index.
  CLEAR gs_last.
  CALL METHOD gr_alvgrid->get_selected_rows
    IMPORTING
      et_index_rows = lt_rows.
  READ TABLE lt_rows INTO ls_rows INDEX 1.
  IF sy-subrc EQ 0.
    gv_index = ls_rows-index + 1.
  ELSE.
    gv_index = 1.
  ENDIF.
  DESCRIBE TABLE gt_last LINES lv_cntid.
  lv_cntid = lv_cntid + 1.
  gs_last-cntid = lv_cntid.
  INSERT gs_last INTO gt_last INDEX gv_index.
  LOOP AT gt_last INTO gs_last FROM gv_index TO gv_index.
Make the new line editable
    PERFORM f9611_style.
  ENDLOOP.
  CALL METHOD gr_alvgrid->refresh_table_display
    EXCEPTIONS
      finished = 1
      OTHERS   = 2.
ENDFORM.                    " f9610_insert_new_line
You can ask questions doubts if any!
