step 1:proc sort the dataset by "PID YEAR"
step2 :in the datastep "SET" it using by PID YEAR
create a temp variable say _SUM and RETAIN _SUM,
reset _SUM=0 on FIRST.YEAR.
T_VALUE=_SUM+VALUE

I guess this will work

Answer / ravi s

step 1 : proc sort; by year name;run;

Step 2: data total (drop = value);
set count_;
by year name;
if first.name then T_value =0 ;
T_value + value;
if last.name then output ;
run;
