Hey all,
i'm trying to figure out how to eliminate repeating attributes in my dataset.
For example, i want:
TICKET_ID STATUS1 STATUS2 STATUS3 STATUS5 STATUS6
to become:
TICKET_ID STATUS
Assuming the statuses are unique.
Please help!
This operation is usually called "going from wide to long". It can be performed with arrays, which offer efficiency and flexiblility, but a simpler way is to use proc transpose:
proc transpose data=have out=want(rename=col1=STATUS);
by ticket_id notsorted;
var status1-status6;
run;
Here are two links that illustrate using arrays & proc transpose

http://www.ats.ucla.edu/stat/sas/modules/widetolong_data.htm
Both methods are also used to go from long to wide.
