I've tried a variety of things. I can get the output to one row per r_id which is what I want but the result is not correct.
If there is no strt_dt for a r_id then we want the earliest creat_dt.
if there is a strt_dt for a r_id we want the earliest strt_dt.
This is what the result should look like

Any help is greatly appreciated. Thanks.
Try next code:
data have;
input @1 r_id $5. @7 creat_dttm mmddyy10. @18 strt_dt mmddyy10. ;
format creat_dttm strt_dt mmddyy10.;

Excellent. That's it. Thank you so much for the help and fast response.

If should be pretty straight forward to translate that into SQL.

That does also work. Thanks.
Hi:
I'm confused by your data and what you say you want:
Why do you show only 1 row per ID in your desired output but show 2 rows for J2256? It is not clear to me whether you expect to see 13 rows in the final output, 6 rows in the final output or 7 rows in the final output. Can you clarify?

I did say in the initial post "I can get the output to one row per r_id which is what I want"
Thanks for the reply.
