Dataset
ssn Amt PLAN Mod
2345 233 9229 26
2345 244 9222 12
1234 222 9229 26

Expected result
ssn Amt PLAN Mod
2345 233 9229 26
1234 222 9229 26

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.
