Hi,
I am new to SAS and I need to know how to limit the number of months to 24.
Every month I upload new data and would like the oldest month to be dropped off.
Any advice?
Are you talking about data sets, variables, or observations? Show some example data.
Months are variables in the data
Depends on how the month variables are named. Here is an example that might be helpful.
data have;
input id date;
format date mmddyy10.;
informat date mmddyy10.;
cards;
1 01/01/2014
2 01/01/2013
3 01/01/2012
;
run;
data want;
set have;
var1=INTCK('Month',date,today());
if INTCK('Month',date,today()) ge 24 then delete;
else output;
run;
proc print; run;
