i am currently trying to solve a problem, but have not managed so far. i am quite new to programming, so it may also be that the solution is very simple.
I have the following table:
My goal is to have only those on my new list that have only one entry.
Can someone please help me here?
Best thanks in advance
The way i would tackle this would be with the datastep.
