ABAP OO: traffic lights in ALV
Instead of going the easy way, I decided to practise a bit of ABAP OO (which I am still quite unfamiliar with), and do ALV list to my new report by using CL_SALV_TABLE class.
This seems to be quite clear if I just follow Rich's great instructions:
The only thing that is not so clear is that how can I add traffic (or led) lights to my ALV list when using class CL_SALV_TABLE. Does someone has an example?
Another bonus question: Do I always have to define the field catalog (with CL_SALV_TABLE) when using internal table of my own type?
