Hi All,
I am doing my first Interactive ALV report using OOPs. There are certain codes given on wiki.scn and other sites. I have tried almost all. But the problem is that I am not getting the output. I have been trying since many hours. I fail to understand where I am lacking. However, I have done 2-3 ALV report using OOPs. I am stuck in drilling part.
Following is the code of a basic report for learning purpose:
