output just the last observation subject and BY date

Hi!  more questions!

 

I have output results that look like this form summing by subject and reset to zero with each new date.  How can I output just the last observation BY date ( so I just get the final sum by date and not the running total)?  These are results from same subject.

 

02OCT2017 81 81
02OCT2017 22 103

02OCT2017 39 142
11DEC2017 93 93
11DEC2017 23 116
11DEC2017 57 173

 

This is outputting the last subject of all dates, but I need last subject at each new date encountered.


data out;
set in
by patient dat;
if last.patient;
run;
