i want the first non missing value of each store?
data test;
input store sales;
cards;
1 .
1 200
1 300
1 .
2 .
2 300
2 150
2 560
3 900
3 560
3 .
;
run;
data want;
set test;
if not missing(sales) then
output;
run;
data want2;
set want;
by store;
if first.store;
run;
Here is a one-step solution, for the sake of efficiency:
data want;
set test;
by store sales notsorted;
ct=ifn(first.store,0,ct);
ct+(first.sales and not missing(sales));
if ct=1;
drop ct;
run;
It's easy with a WHERE statement:
data want;
set have;
by store;
if first.store;
where sales > .;
run;
