1 500
1 200
1 100
2 900
2 550
2 200
3 1900
3 1300
3 750
3 500
Thanks & Regards
Mona
Hi Mona,
the solution I posted here, is exactly what you need, expect you want to use 2 instead of 4.
proc sort data=have;
by customerID descending amount;
run;
data want;
set have;
by customerID;
if first.caseID then count=0;
count+1;
if count <= 2;
run;
