CTE into temp table

Question

I have query with many CTE:
;WITH CTE AS(...), CTE1 AS(....), CTE2 AS (...), CTE3 AS(...)
CTE4 AS(...), CTE5 AS(...), CTE6 AS(...), CTE7 AS(...), CTE8 AS(...), CTE9 AS(...), CTE10 AS(...), CTE11 AS(...)
SELECT * FROM CTE9 INNER JOIN CTE11 ON....
The last select works 3 minutes, but until CTE11 everything works in 1 second.
Is it possible to store CTE9 and CTE11 into temp table? (the same select form temp tables would execute immediately)
CTE9 and CTE11 has inside access to previous CTE's, so I can't break the query before CTE11 unless I create every CTE as temp table.

Answer 1

"I think it is too fragile."
If I store in physical table instead of temp table than if server go down, at least I will
have my data stored.
And it is not critical if this records are not available in main table for some time.
It could be solution, but requires some maintenance work in case server goes down or any other
uncatchable error .
But i guess I will just disable escalation.
My problem is quite simple. I have table "dbo.Stock" where is stock of products in warehouse. Lets say 1 million of products with some quantity. Each quantity of product has some ownership.
For example: i have quantity 1000 of product A. 500 quantity belongs to company1, 300 to company2 and 200 to company3.
Then at some time, I have to rearrange the ownership of lets say 200000 products(20%). (could be any number, more or less).
Until new ownership is not known, this stock should not be available for any operation - so, it is no problem, if this stock doesn't exists in table "dbo.Stock" at calculation time. But for other stock(800.000 products) all operations must be available.
So, i move(delete) this 200.000 products out of stock table and calculate ownership. This calculation
runs for 10 minutes. Then I move this stock back to the table(PK of most of the records is different now, so couldn't be update anyway).
Can you image that this table is locked for 10 minutes and it is very frequent one? Everything would stop for 10 minutes and i will get fired :)
What function? Do you have some description? I'm curious, maybe get some idea :)
