Hello Experts,
could somebody please xplain me how this formula works? I can't manage it 
Everything I do it does not work. I do not have a requirement, I just want to understand how this works and how the formula has to be integrated in the report. Unfortunately, as usual at SAP, there is no useful help available.
There is a similar thread on SCN, but to be honest, I cant get this work.

Ty in advance,
Karsten
