If x has more than one y associated with it, make it into a list

[jdmarks3]

I'm trying to sort my data the following way:

I have Case_Group_Name (x) and State (y). I want the list of the Case_Group_Names if they are located in multiple states. The Case_Group_Names with only one state I want deleted. 

I'm thinking this is a proc sort procedure, but I'm not sure how to go about it; I just started out using SAS. Thanks you.

If I understand your question, try this:

proc sort data = in;
  by x;
run;

data multi;
  set in;
  by x;
  if not( first.x & last.x );
run;

One of the issues to consider is whether the same Case_Group_Name could appear multiple times within the same State. 

If the Case_Group_Name / State combinations are unique, the suggested solution will work.
