Hi!
I want to create a variable who goes frome 1 to 12 based on the date of a test (like first test of the year, second test of the year etc) Here is a little example of what I want it to look like:
Anyone can teach me?
Thanks a lot!
Annie
please try
data have; input cow$ irtest:ddmmyy10. scc; cards; daisy 10/7/2017 200 maggy 10/7/2017 120 lily 10/7/2017 98 daisy 11/8/2017 89 maggy 11/8/2017 120 lily 11/8/2017 98 ; proc sort data=have; format irtest date9.; by cow irtest; run; data want; set have; by cow irtest; retain no_test; if first.cow then no_test=1; else no_test+1; run;

Thank you very much!
Can be solved by sorting data by Cow and JR_Test and a datastep with first and retain to create no_test.
data want; set have_sorted; by Cow; length no_test 8; retain no_test; if first.Cow then no_test = 0; no_test = no_test + 1; run;
The code is untested, because you haven't provided data in usable form.
