I have a large data that includes multiple observations for each ID. 

If I only wanted to select the first entry of each ID, then the below code works. 

If I wanted to select the first 5 entries of each ID, then what coding could I use?

Thanks for your help in advance. 

 

data want;

set have;

by id;

if first.id;

run;

You have to count the obs per ID, code is untestet:

data want;
  set have;
  by id;
  length counter 8;
  retain counter;
  if first.id then counter = 0;
  counter = counter + 1;
  if counter <= 5;
run;
