Dataset with multiple level classification vars

[Jsendzik]

Hello,

I'm trying to make data sets that look like this.

YEAR_Month	Class	Student	Distinct Count
2014	ALL	ALL	100
2014_01	A	ALL	50
2014_01	B	ALL	50
2014_01	A	1	25
2014_01	A	2	25
2014_01	B	1	25
2014_01	B	2	25

I'm currently just using a bunch of proc SQL statements and then using a data step to union them all back together. I was wondering if you all knew of a SAS procedure that will generate the same results but with less code, as you can imagine the code gets pretty redundant as the count of classification variable increases. Any help would be much appreciated.

Thanks!

I think you forget part of the story.

What do you mean?

I would be helpful to describe the input.

You can get what you want with PROC SUMMARY;

proc summary;

  class year_month class student;

  output out=counts;

  run;
