;run;

in the above program there are 2 different ssn(social secuirty number), i want to count how many times he has paid.Till here it is working fine .But i dont want to include the last payment or you can say exclude the latest date for every ssn and then output all others as you can see below.

Pls help!!

proc sort data=test;by ssn;run;

data a c1 c2 c3;
set test;
by ssn;
if first.ssn then c=0;
c+1;
if c=1 then output c1;
if c=2 then output c2;
if c=3 then output c3;
run;

I don't understand what you try to do with c1, c2 and c3 in you data step? Do you want to create separate datas sets for each count or? 

If you simply want to exclude the latest payment, then do

data want;
   set test;
   by ssn; 
   if first.ssn then c=0;
   c+1;
   if not last.ssn;
run;

Hi dray,

u are right , i wanted to put records with count as 1 ,2,3 in separate datasets and ignore the last one and do some calculations with it.

Anyway ur solution is perfect.

Thanks!
