Outer Join not functioning

Question

I have a query as shown below
select w.columns1, w.cloumn2, w.counter
Select a.columns1, a.cloumn2, a.rownum counter
from (subquery a
union
subquery b)
) w
view b
where
w.counter(+) = y.counter,
The view has standard 12 records with a value 0. Now my problem is that for each product_key in main query, if i receive less then 12 records then the oter join with view should halp me to fetch 12 records for a particular product.
But soehow the outer join ins not working.
HELP required ASAP
Thanks in Advance
