Hello,

 

I was having trouble using the last value in my groups as the value for all members in my groups. Basically, I want whatever the last value in the group is to be the value for all members in that group.

What I have: 

data Have;
input ID Name $;
cards;
1 ''
1 Yes
2 '' 
2 No 
3 ''
3 '' 
3 Yes
4 No
5 '' 
5 Yes 
6 No 
8 Yes 
;
run;

Which looks like:

But What I WANT:

JMagenta_1-1678479569603.png

How can I achieve my goal? Please help.

 

Thank you in advance,

J

This kind of worked, only I am now missing some data somehow. I also have duplicates.
