Proc SQL is one solution. .
Proc Sql;
create table Supervisors as
select b.manager as TwoUp, a.Manager as OneUP, a.Employee
from datasetname as a left join datasetname as b on
a.manager = b.Employee
;
quit;
Give another hash ,
data have;
input employee :$8. manager:$8.;
cards;

;
run;quit;
data want;
length twoup oneup $ 8;
if _n_=1 then do;
if 0 then set have(rename=manager=_m);
declare hash h(dataset:'have(rename=(manager=_m))');
h.definekey('employee');
h.definedata('_m');
h.definedone();
end;
set have;
if h.find()=0 then do;
oneup=_m;
if h.find(key:oneup)=0 then twoup=_m;
end;
drop _m manager;
run;
