How to display different icon within WDA alv table base on row data ?

Question

Hi,
is that possible to display different icon for every row within ALV table depending on the row data ?
for instance if the status 'S' display ~Icon/SuccessMessage and 'E' display ~Icon/ErrorMessage ?
because base on this code below i only can set 1 icon for the whole row data.
LOOP AT lt_columns ASSIGNING <fs_column>.
    CASE <fs_column>-id.
      WHEN 'ICO'.
        CREATE OBJECT lr_caption.
           lr_caption->set_image_source( value = '~Icon/SuccessMessage').
           <fs_column>-r_column->set_cell_editor( lr_caption ).
    ENDCASE.
  ENDLOOP.
Thank you in advance.

Hello,
Yes it is possible to display different images based on data.
For that what you can do is create one attribute 'STATUS' of type string in context node which you are mapping to ALV.
And fill that attribute with the path to image based on your requirement like for status 'S' set the attribute to ~Icon/SuccessMessage and if status is 'E', set it to ~Icon/ErrorMessage at runtime.
Now in the settings for ALV use the following code:
* Display icon in column seatsocc
  DATA: lr_column TYPE REF TO cl_salv_wd_column,
        lr_image TYPE REF TO cl_salv_wd_uie_image,
        lv_icon TYPE string.
  lr_column = lv_model->if_salv_wd_column_settings~get_column( 'SEATSOCC' ).
  CREATE OBJECT lr_image.
  lr_image->SET_SOURCE_FIELDNAME( 'STATUS' ).
  lr_column->set_cell_editor( lr_image ).
in the above code, column 'SEATSOCC' will be displayed as an icon.
Sample code to fill the attribute 'STATUS'
LOOP AT lt_flights INTO ls_flight.
    lv_seatsfree = ls_flight-seatsmax - ls_flight-seatsocc.
    IF lv_seatsfree = 0.
      ls_flight-status = 'ICON_RED_LIGHT'.
    ELSEIF lv_seatsfree <= 50.
      ls_flight-status = 'ICON_YELLOW_LIGHT'.
    ELSE.
      ls_flight-status = 'ICON_GREEN_LIGHT'.
    ENDIF.
    MODIFY lt_flights FROM ls_flight.
  ENDLOOP.
Hope this helps!
