If you know that your data is sorted, but not in a pre-defined sorting sequence (such as ASCII, ANSI etc).
I.e. month names.
The benefit is that you still will be able to use BY group processing in the data step/PROCs.

Notsorted is for when data is grouped logically, but not necessarily in alphabetic or numeric order. I.e.
The data A is grouped together but is not sequential to B.
