I hope someone can help me. I have a large data sets with four variables. The first 3 variables have duplicate rows where only the last variable is a different number. How do I sum the last variable for all the combinations of the first three variables? So if the first 3 variables as in B_CODE P_CODE and DATE have the same combination I want to sum the the ACTUAL variable.
I think this is what you are asking for. It creates a SAS data set holding the totals of the last variable, for every possible combination of the first three:
proc summary data=have nway;
class var1 var2 var3;
var var4;
output out=want (drop=_type_ _freq_) sum=total_var4;
run;
The program requires some tweaking if it is possible that any of your first three variables ever take on a missing value.

.I think you're going to need to post some sample data so we understand what you want.
Ideally include what you have, what you want, and what you've tried.
