How do I restrict this to give me only the max date record per each Item # per WH_ID? I only want 1 record for Truck 41 with the latest date of 12/13/11.

Select
invent.[Location Code] AS WH_ID
,invent.[ITEM NO#] as ItemNo
,invent.[Posting Date] as Date
,invent.[Remaining Quantity] as Qty
,invent.[Unit Cost] as Cost
FROM OPENROWSET
('MSDASQL', 'Driver={Microsoft Text Driver (*.txt; *.csv)};
DefaultDir=Z:\\mydata;','select * from Itemledger.txt')invent
Left join (SELECT [Location Code],[ITEM NO#],max([Posting Date] )[Date] FROM OPENROWSET
('MSDASQL', 'Driver={Microsoft Text Driver (*.txt; *.csv)};
DefaultDir=Z:\\mydata;','select * from Itemledger.txt')
Group by [Location Code], [ITEM NO#], [Posting Date]) B
On B.[Location Code] = invent.[Location Code] and B.[ITEM NO#] = invent.[ITEM NO#]
Where invent.[Remaining Quantity] > '0'
and invent.[ITEM NO#] = '10-BH-5'
order by invent.[ItemNo]

This is my result:
WH_ID ItemNo Date Qty Cost
MAIN 10-BH-5 08/07/12 20 0.93
TRUCK 13 10-BH-5 09/01/11 6 1.52
TRUCK 27 10-BH-5 03/03/11 6 1.44
TRUCK 41 10-BH-5 10/26/11 2 1.52
TRUCK 41 10-BH-5 10/26/11 2 1.52
TRUCK 41 10-BH-5 12/13/11 4 1.51
TRUCK 41 10-BH-5 12/13/11 4 1.51
TRUCK 51 10-BH-5 02/22/12 1 1.09
