displaying traffic lights in alv grid report?

Hi everyone,

I have an alv grid report.I m using the FM reuse_alv_grod_display to display my alv report.I am passing the fieldcatalogue automatically.I m getting the output perfectly.Now i have to add traffic lights to that alv report.

Since i m passing the fieldcatalogue automatically i m confused to display the traffic lights?

any suggestions please?

Thank you.
