Standard report copy to Z

Hello friends

I copying a standard report and making Z report. The Tcode is "KE5Z", it is a Drill down report. I am going through the program and I found that the program name and tcode of standard in mentioned many times, I think I need to change them please confirm me. Also one major problem the ALV Header is also not coming, I have been told to copy the ALV GUI from se41 and activate it, can you guide me how? The error is "Status STANDARD_GRID of the user interface SAPLRSTI missing"

Thanks in advance
