The by statement causes and error because the dataset ex is not properly sorted.

The retain statement without a variable has no effect.

Could you please post the intended result?

I agree with Kurt, you need to show what your intended result is.  Here is a guess:

 

data want;

set have;

by pi test;

if first.test=0 then blfl='Y';

run;
