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 (

                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)
