This document helps in understanding the code to be implemented for displaying report using CL_SALV_TABLE for showing TRAFFIC LIGHTS
- Generally when displaying TRAFFIC LIGHTS, we use set_exception_column() method. When used this method, column text is displayed as ‘EXCEPTION’ for TRAFFIC LIGHTS column.
- Using the below code we set our custom text for the same column i.e in place of EXCEPTION for TRAFFIC LIGHTS column we can use our custom code.

Output looks like below:
Use the below code for changing the text of ‘EXCEPTION’ to custom text(here I used ‘STATUS’)
