Hi, I have a dataset that looks like this:
ID TRT VID OUTCOME
1 0 1 1
1 0 2 0
1 0 1 1
1 0 2 0
2 1 1 1
2 1 2 1
I would like my final dataset to look like this:
ID TRT VID OUTCOME
1 0 1 1
2 1 1 1
I would like to only have unique ID numbers for when outcome=1 in a separate dataset, so that I can then run analyses on those ID numbers. Thank you!

If you don't need the other variables at all easiest may be:
Proc sql; create table idonly as select distinct id from yourdatasetname; quit;

Thank you, that is exactly what I was looking for!
