Multiple selection in DISPLAY only ALV GRID

Question

Hi,
I would like to make the rows of the ALV Grid Display only at the same time I would like to make multiple selection possible.
Multiple selection is possible by giving EDIT = 'X' at the layout level. But then if we give EDIT = ' ' at the fieldcatalogue level or no_input = 'X' at the layout level it is still in Editable mode. Kindly help me.
Thanks

Hi,
Setting and getting selected rows (Columns) and read line contents
You can read which rows of the grid that has been selected, and dynamic select rows of the grid using methods get_selected_rows and set_selected_rows. There are similar methods for columns.
Note that the grid table always has the rows in the same sequence as displayed in the grid, thus you can use the index of the selected row(s) to read the information in the rows from the table. In the examples below the grid table is named gi_sflight.
Data declaration:
DATA:
Internal table for indexes of selected rows
gi_index_rows TYPE lvc_t_row,
Information about 1 row
g_selected_row LIKE lvc_s_row.
Example 1: Reading index of selected row(s) and using it to read the grid table
  CALL METHOD go_grid->get_selected_rows
    IMPORTING
      et_index_rows = gi_index_rows.
  DESCRIBE TABLE gi_index_rows LINES l_lines.
  IF l_lines = 0.
    CALL FUNCTION 'POPUP_TO_DISPLAY_TEXT'
         EXPORTING
              textline1 = 'You must choose a valid line'.
    EXIT.
  ENDIF.
  LOOP AT gi_index_rows INTO g_selected_row.
     READ TABLE gi_sflight INDEX g_selected_row-index INTO g_wa_sflight.
    ENDIF.
  ENDLOOP.
Example 2: Set selected row(s).
  DESCRIBE TABLE gi_index_rows LINES l_lines.
  IF l_lines > 0.
    CALL METHOD go_grid->set_selected_rows
        exporting
          it_index_rows = gi_index_rows.
  ENDIF.
Make an Exception field ( = Traffic lights)
There can be defined a column in the grid for display of traffic lights. This field is of type Char 1, and can contain the following values:
1 Red
2 Yellow
3 Green
The name of the traffic light field is supplied inh the gs_layout-excp_fname used by method set_table_for_first_display.
Example
TYPES: BEGIN OF st_sflight.
        INCLUDE STRUCTURE zsflight.
TYPES:  traffic_light TYPE c.
TYPES: END OF st_sflight.
TYPES: tt_sflight TYPE STANDARD TABLE OF st_sflight.
DATA: gi_sflight TYPE tt_sflight.
  Set the exception field of the table
    LOOP AT gi_sflight INTO g_wa_sflight.
      IF g_wa_sflight-paymentsum < 100000.
        g_wa_sflight-traffic_light = '1'.
      ELSEIF g_wa_sflight-paymentsum => 100000 AND
             g_wa_sflight-paymentsum < 1000000.
        g_wa_sflight-traffic_light = '2'.
      ELSE.
        g_wa_sflight-traffic_light = '3'.
      ENDIF.
      MODIFY gi_sflight FROM g_wa_sflight.
    ENDLOOP.
  Name of the exception field (Traffic light field)
    gs_layout-excp_fname = 'TRAFFIC_LIGHT'.
  Grid setup for first display
    CALL METHOD go_grid->set_table_for_first_display
      EXPORTING i_structure_name = 'SFLIGHT'
                              is_layout               = gs_layout
      CHANGING  it_outtab                 = gi_sflight.
Color a line
The steps for coloring a line i the grid is much the same as making a traffic light.
To color a line the structure of the  table must include a  Char 4 field  for color properties
TYPES: BEGIN OF st_sflight.
        INCLUDE STRUCTURE zsflight.
      Field for line color
types:  line_color(4) type c.
TYPES: END OF st_sflight.
TYPES: tt_sflight TYPE STANDARD TABLE OF st_sflight.
DATA: gi_sflight TYPE tt_sflight.
Loop trough the table to set the color properties of each line. The color properties field is
Char 4 and the characters is set as follows:
Char 1 = C = This is a color property
Char 2 = 6 = Color code (1 - 7)
Char 3 = Intensified on/of = 1 = on
Char 4 = Inverse display = 0 = of
     LOOP AT gi_sflight INTO g_wa_sflight.
      IF g_wa_sflight-paymentsum < 100000.
        g_wa_sflight-line_color    = 'C610'.
      ENDIF.
      MODIFY gi_sflight FROM g_wa_sflight.
    ENDLOOP.
Name of the color field
gs_layout-info_fname = 'LINE_COLOR'.
Grid setup for first display
CALL METHOD go_grid->set_table_for_first_display
      EXPORTING i_structure_name = 'SFLIGHT'
                             is_layout                = gs_layout
      CHANGING  it_outtab                 = gi_sflight.
Refresh grid display
Use the grid method REFRESH_TABLE_DISPLAY
Example:
CALL METHOD go_grid->refresh_table_display.
ALV Grid Control with column and row selection
Selecting and Deselecting Rows
Use
Depending on where the ALV grid control is used, there are various methods for selecting and deselecting cells and rows:
If no pushbuttons are displayed on the left edge of the list:
You can only select one row at a time.
You can select multiple rows.
If pushbuttons are displayed on the left edge of the list:
You can select several rows or individual cells.
You can select several rows as well as several cells or individual cells.
Procedure
If no pushbuttons are displayed on the left edge of the list, you select a row by clicking an entry in the row.
If pushbuttons are displayed on the left edge of the list, you select a row by clicking the pushbutton on the relevant row.
In this case, you select the relevant cell by selecting the entry in the row.
In both cases:
To select several rows, press the Shift button and choose the cells as described above.
Adjacent rows:
Select a row, choose Shift or Control, and select the desired rows,
or
Choose Shift, and select the first and the last of the desired rows,
or
Select a row, keep the mouse button pressed, and pass over the desired rows.
Rows that are not adjacent:
Select a row, choose Control, and select the desired rows.
All rows:
You can only select all rows at once if pushbuttons are displayed on the left side of your list. To select all rows, choose .
To deselect individual rows, press the Ctrl button and click the relevant row.
Result
The selected cells have an orange background. The position of your cursor is indicated with a yellow background.
