set HAVE;
by GVKEY YEAR;
if FIRST.YEAR THEN SUM=0;
SUM+TDC1;
run;

proc sql;
create table WANT as        /*Select the sum per group and paste it to the observation with CEOANN = "CEO"*/
select a.*, b.SUM as SUM_5_EXEC
from pre_want as a left join (select YEAR,GVKEY,SUM
							  from pre_want
							  where EXECRANKANN=5) as b

		on  (a.GVKEY=b.GVKEY and a.YEAR=b.YEAR and a.CEOANN="CEO")

order by GVKEY, YEAR, EXECRANKANN    
;
drop table pre_want;  /*Deletes the pre_want table*/
quit;
