Hi,

Observe the code:

REPORT ALV_LIGHTS.* Published at SAPTechnical.COMTYPES: BEGIN OF ty_alv,

lights(1) TYPE c, "Exception, Holding the value of the lights

text(20) TYPE c, "some text

END OF ty_alv.DATA: gs_alv TYPE ty_alv,

gt_alv TYPE TABLE OF ty_alv,

gr_alv TYPE REF TO cl_salv_table,

gr_columns TYPE REF TO cl_salv_columns_table.START-OF-SELECTION.

gs_alv-lights = '1'. "Color red

gs_alv-text = 'RED SIGNAL'.

APPEND gs_alv TO gt_alv. gs_alv-lights = '2'. "Color yellow

gs_alv-text = 'YELLOW SIGNAL'.

APPEND gs_alv TO gt_alv. gs_alv-lights = '3'. "Color green

gs_alv-text = 'GREEN SIGNAL'.

APPEND gs_alv TO gt_alv. CALL METHOD cl_salv_table=>factory

IMPORTING

r_salv_table = gr_alv

CHANGING

t_table = gt_alv. gr_columns = gr_alv->get_columns( ). gr_columns->set_exception_column( value = 'LIGHTS' ). CALL METHOD gr_alv->display.

Hi, Pass below codes as texts for the push buttons:

@0A@ - Red
@09@ - Orange
@08@ - Green

Below code can help you understanding handling normally without pushbuttons:

DATA: ok_code TYPE syucomm.

TYPES: BEGIN OF ty_data,
         num TYPE i,
         icon TYPE icon_d,
       END OF ty_data.

DATA: wa_data TYPE ty_data,
      i_data TYPE TABLE OF ty_data.

DATA: i_fieldcat TYPE lvc_t_fcat,
      wa_fieldcat TYPE lvc_s_fcat.

DATA: g_cust_cont   TYPE REF TO cl_gui_custom_container,

      g_container   TYPE scrfname VALUE 'GRID1',

      g_grid        TYPE REF TO cl_gui_alv_grid.

START-OF-SELECTION.

  DO 10 TIMES.
    wa_data-num = sy-index.
    IF sy-tabix < 4.
      wa_data-icon = '@0A@'.
    ELSEIF sy-tabix < 7.
      wa_data-icon = '@09@'.
    ELSE.
      wa_data-icon = '@08@'.
    ENDIF.
    APPEND wa_data TO i_data.
  ENDDO.

END-OF-SELECTION.
