Taking a guess at what you hope to achieve ...

This program would move in the right direction, by selecting observations with a nonmissing value for BA:

data want;
   set new;
   where ba > .;
run;

And this program would take it a step further, selecting just the last such observation for each ID:

data want;
   set new;
   where ba > .;
   by id;
   if last.id;
run;

If you want to read all observations, update your code as follows

Data new;
input id ba;
infile datalines missover;
datalines;
101 
101 
101 
101 
101 5
102 
102 
102 
102 9
;
run;
