BMM model for subquery

Question

Hi All,
I have a requirement to pull the generate sql for the report.
select distinct T.Sum,A.Region,A.Section
from A
join ( select sum(Amount),Region from B
group by Region)T
B on A.Region=T.Region
What is the best practice to generate this query with sub query in BMM layer?
Do we need to create a view ( select sum(Amount),Region from B
group by Region)with subquery in physical layer and join with Table A
or there is other better way of modelling in BMM layer.
Thanks,
Surya

Hi All,
Thanks for your kind reply. The problem is that there are 3-4 layers of nested queries. How can we tackle these issue on BMM layer?
for example
select distinct X.Amount,C.Amount2,C.Region,C.Section
select distinct T.Sum,A.Region,A.Section
from A
join ( select sum(Amount),Region from B
group by Region)T
B on A.Region=T.Region)X
on X.Region=C.Region and X.Section =C.Section
group by
C.Amount2,C.Region,C.Section
Thanks,
Surya
