i am trying to identify if a customer id has different risk grades per facility. i am completely stumped as to how to do it.as an example:

 

The following (customer 1) is what I am trying to identify from a dataset: 

 

Customer   Facility   Grade

customer 1  1          A

customer 1  2          B

customer 2  1          A

customer 2   2        A

customer 2   3       A

 

Any idea how i can segment them?

Or perhaps you just wanna have flag variable as indicator in the form of 1's and 0s

 

proc sql;
create table want as
select *,count(distinct grade)>1 as flag
from have
group by customer;
quit;
