Interactive ALV using OOPS

Hi Experts,

I am trying to create an Interactive ALV report using OOPS concept. I have written the logic for the same. While checked in debugging, I am getting the values in respective internal table, but not on screen. Can you suggest, what is wrong in my program.

As a rule-of-thumb when you write ABAP code and refer to ABAP technical names, always use upper case.

when submitting some code along with question, please press the code button it becomes easier to read for others

You're using PERFORMs, so your program isn't OOPs. (Even though you're using classes). PERFORMs have been obsolete for years. Use a class with methods.

Furthermore, when posting code, use the little button in the editor marked "code", to make it easier to read.

If you edit your question and use the code button, and remove the commented out lines that just make it hard to read, I might be inclined to help further.

No answer from OP → vote -1 and I won't answer OP future questions.
