I need to keep only one row for this ppt if it has row for both the plans (9229,9222) . I need to just poulate row for plan 9229. How can this be done with out dropping any variable.

Double DO loop

data want;
do until (last.ssn);
  set have;
  by ssn notsorted;
  if plan = "9222" then has_9222 = 1;
end;
do until (last.ssn);
  set have;
  by ssn notsorted;
  if plan = "9229" and has_9222 then output;
end;
drop has_9222;
run;

Untested, for lack of usable data.
