Hi,
for a button with traffic light icon you need a field in your field catalogue with
- data element ICON_L4 or other data element for domain ICON
- value for ICON set to 'X'
- value for HOTSPOT set to 'X'
- value for STYLE set to CL_GUI_ALV_GRID=>MC_STYLE_BUTTON
The values for the traffic light fields are ICON_GREEN_LIGHT, ICON_YELLOW_LIGHT and ICON_RED_LIGHT.
For access to TYPE-POOL ICON please add the folowing line to your code:
TYPE-POOLS: icon.
Regards,
Klaus
