Add this
options dkricond=nowarn dkrocond=nowarn ;
before data step.
Same as before. Now the output dataset has only 'Date' variable. Other variables are gone.
To limit your data you can use a WHERE statement in a data step or proc, assuming you have a SAS date.
e.g.
where year(date)=2004;
How to use the data set decile? That depends on how you want to use it. I suspect you'll need to merge it in but you'll have to provide a sample input/output for more detailed help.
