Classic use of the IDGROUP Option in Proc Summary

 

proc summary data=have nway;
   class company_name year type;
   var percent_shares;
   output out=want(drop=_:) idgroup (max(percent_shares) out[2] (percent_shares) = largest);
run;

  retain first_largest second_largest flg;
  if first.type then do;
    flg=1;
    first_largest =percent_shares;
    second_largest=.;

  else flg+1;

  if flg=2 or (first.type and last.type) then do;
    second_largest=percent_shares;
    output;
  end;
  drop percent_shares flg;
run;

 It would be helpful if you could present the sample data in a usable form in the DATA step if possible.
