I get error when executing it in SQL 2008.The Parallel Data Warehouse (PDW) features are not enabled

I can do this in SQL 2012 but I want similar output in SQL 2008
declare @Buckets table (ID char(2), FullCapacity int)
declare @Filler table (ID char(2), Filler int)

insert into @Buckets values
('B1', 100),
('B2', 50),
('B3', 70)

insert into @Filler values
('F1', 90),
('F2', 70),
('F3', 40),
('F4', 20)

;with fillerCte as
(
select
ID,
Filler,
sum(Filler) over (order by ID) as TotalFill
from @Filler
),
BucketCte as
(
select
ID,
FullCapacity,
sum(FullCapacity) over (order by ID) - FullCapacity as RunningTotalCapacity
from @Buckets
)
select
b.ID,
b.FullCapacity,
case
when f.TotalFill < b.RunningTotalCapacity then 0
when f.TotalFill > b.RunningTotalCapacity + b.FullCapacity then b.FullCapacity
else f.TotalFill - b.RunningTotalCapacity
end as CurrentAmount
from fillerCte as f
cross join BucketCte as b
order by f.ID, b.ID

I have not added filler table, in the script there is a single filler value. I want to use filler table but when I use filler table the CTE is not working

Please ignore the script. The values are just as example.
