Its a LASR Table, but the real root of the data are from a DBMS. By the way. With regards to your Maxim 3. I want to take jus the last quarter if that quarter occurs more then once in a type. How can I achieve that?

So something converts the DBMS data to a LASR table. This is the process that needs to be looked at.

Do you have a direct connection to the DBMS via SAS/ACCESS, or do you read an unload from the DB into SAS?

To retrieve the last entry for a quarter, sort by type, quarter and an optional item (e.g. date), then do

data compressed / view=compressed;
set have;
by type quarter;
if last.quarter;
run;

Since the view will be executed while the data is processed, it won't eat unnecessary disk space.

I received the same output I received when I ran @Kurt_Bremser's transpose snippet

ERROR: The ID value "K-11" occurs twice in the same BY group.
ERROR: Too many bad BY groups.

You must have data like this :

K-11     202001    1
K-11     202101    2
K-11 202101 22 K-11 202003 K-12 202101 3 K-12 202102 K-12 202002 1 K-13 202002 2 K-13 202103 3 K-13 202104 2

 You need figure out what output you want to see for this data.

@Ksharp. Read my new post under @Kurt_Bremser's last post. I've posted a new dataset.
