Hi,

Assuming the logic s to just take the first occurence (and its sorted):

data want;

set have;

by id;

if first.id;

run;

This will get you the result you want, but based on the way you ask your question I'm not sure that you don't want to use proc format:

data have;

infile cards dsd;

input id$ type$;

cards;

1234,old

1234,new

2345,old

4567,old

5678,new

;

proc sort data=have;by id type;

data want;

set have;

by id;

if last.id;

run;
