Hi Santosh,

In your ALV table/structure define field 1 char like 'rob'.

• define a single character column as a traffic light

• '1' = red, '2' = yellow, 3 = 'Green'

alv_layoutcat-lights_fieldname = 'ROB'.

it_list_data-rob = 1.

APPEND it_list_data.

it_list_data-rob = 2.

APPEND it_list_data.

it_list_data-rob = 3.

APPEND it_list_data.

ALF Function module something like this then

• Call ABAP/4 List Viewer

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

EXPORTING

i_callback_program = 'ZREPORT'

is_layout = alv_layoutcat

it_fieldcat = it_fieldcat

TABLES

t_outtab = it_list_data.

Hi Santosh ,

Here is a sampla code for the same

TYPE-POOLS : SLIS.

DATA : BEGIN OF IT_1 OCCURS 0 ,
           MATNR TYPE matnr ,
           FLAG TYPE C ,  " added for the traffic control
       END OF IT_1.

SELECT MATNR INTO TABLE IT_1 " Select Data
UP TO 10 ROWS
FROM MARA.

DATA : CATALOG TYPE SLIS_T_FIELDCAT_ALV ,
       WA_CATALOG TYPE SLIS_FIELDCAT_ALV ,
       LAYOUT TYPE SLIS_LAYOUT_ALV .

WA_CATALOG-FIELDNAME = 'FLAG'.
WA_CATALOG-TABNAME = 'IT_1'.
APPEND WA_CATALOG TO CATALOG.

WA_CATALOG-FIELDNAME = 'MATNR'.

LOOP AT IT_1.
FLAG_T = SY-TABIX MOD 2.

MODIFY IT_1.

ENDIF.

so rem all you need to do is add a feild in internal table for the traffic signal , assign values 0 , 1, 2 to it and last specify the name of this feild in the layout.
