LEFT JOIN
dbo.vBranch AS br WITH (nolock) 
ON a.Branch = br.Branch
group by a.Volume, br.SalesArea, br.Branch)

Answer 1

You are missing alias for subquery try out this.

SELECT SalesArea, Branch, Volume
from
(select 
br.SalesArea as SalesArea
,br.Branch as Branch
, sum(a.Volume) as Volume
FROM dbo.vDetail a with (nolock) 
LEFT JOIN
dbo.vBranch AS br WITH (nolock) 
ON a.Branch = br.Branch
group by a.Volume, br.SalesArea, br.Branch) as x

Answer 2

Every select from subquery needs an alias. Just add an "X" in the end that will become the name of the table

NOT OK:

select * from (
   select * from your_table
) 

OK:

select * from (
   select * from your_table
) X

Answer 3

You need alias name for a derived table

SELECT SalesArea, Branch, Volume 
from 
(select  
br.SalesArea as SalesArea 
,br.Branch as Branch 
, sum(a.Volume) as Volume 
FROM dbo.vDetail a with (nolock)  
LEFT JOIN 
dbo.vBranch AS br WITH (nolock)  
ON a.Branch = br.Branch 
group by a.Volume, br.SalesArea, br.Branch) as T
