Difficult Left Join

MY attached code works...I create the #temp table...do my join...and the output is what we want to see.

However...is there a way to NOT create a temp table and do the Left Join with my #temp select as a table in the left join section?

Instead of this...join to my select instead of a temp table
....Left Join #temp z on Left(a.afsSource,7) = z.src
Begin
		select left(afssource,7) src,
				 (1 -sum(case when (afsstatus = 1) then afsamount else 0 end)/sum(afsamount)) *100 as percentHeld
		Into #temp
		from proc_cfa.dbo.P_AvailableForSale  
		group by left(afssource, 7)
		order by left(afssource,7)
	Select	a.afsid,
			a.afsSource,
			case when Left(a.afsSource,2) = 'LT' then 
					lt.status else 
					ss.status end as [status],
			a.afsDate,
			a.afsAmount,			
			a.afsSourceDetail,
			a.afsStatus,
			IsNull(a.afsTransaction,0) as afsTransaction,
--			100 * (1-a.afsAmount / sum(x.afsAmount)) as pctHeld,
			z.percentHeld as pctHeld
	From	proc_cfa.dbo.P_AvailableForSale a
					Left Join proc_lt.dbo.P_Deals lt ON SubString(a.afsSource,4,4) = lt.DealID
					Left Join crmprod_01.dbo.P_Deals ss ON SubString(a.afsSource,4,4) = ss.DealID
					Left Join proc_cfa.dbo.P_AvailableForSale x on a.afsSource = x.afsSource
					Left Join #temp z on Left(a.afsSource,7) = z.src
	Where	a.afsTransaction = 0
			and
			(
				(a.afsAMount > @minAmount - 1 and a.afsAMount < @maxAmount + 1)
					and
				(YEAR(a.afsDate) > @startYear - 1 and YEAR(a.afsDate) < @endYear + 1)
					and
				case when Left(a.afsSource,2) = 'LT' then 
					lt.status else 
					ss.status end = 
						IsNull(@dealStatus,case when Left(a.afsSource,2) = 'LT' then 
									lt.status else 
									ss.status end)
			)
	group by	a.afsid, a.afsSource, a.afsSourceDetail, a.afsDate, a.afsAMount, 
				a.afsTransaction, a.afsStatus,ss.status, lt.status, z.percentHeld
	Order By	a.afsSource,a.afsSourceDetail, a.afsid

you could use WITH construct:
Begin
;with temp as (

--                Into #temp
                from proc_cfa.dbo.P_AvailableForSale  
                group by left(afssource, 7)
                order by left(afssource,7)

Hi,

Without #temp table
