Items sold for January 2010 query

Question

Hi Experts,
I need to create a query for a client that want to see all the Item Codes, Item Description, On hand quantity (at this point in time) and the Quantity on Invoices for a specific month. (Quantity only on AR Invoices, not Credit memos)
Here is what I did so far, but the 'January 2010 QTY' is the whole quantity and not just January's. Any help would be appreciated.
SELECT T0.[ItemCode], T0.[ItemName], T0.[OnHand], SUM(T1.[Quantity]) as 'January 2010 QTY'
FROM [dbo].[OITM]  T0 INNER JOIN INV1 T1 ON T0.ItemCode = T1.ItemCode INNER JOIN OINV T2 ON T1.DocEntry = T2.DocEntry
GROUP BY T0.[ItemCode], T0.[ItemName], T0.[OnHand]

HI Marli,
Try below query for monthly analysis :
Declare @Year Numeric
Set @Year='2010'
SELECT @Year,T0.[ItemCode], T0.[ItemName], T0.[OnHand],
          sum(Case DATENAME(month,T2.DocDate) when 'January' then T1.Quantity   else 0 end) as [January Qty],
          sum(Case DATENAME(month,T2.DocDate) when 'February' then T1.Quantity   else 0 end) as [February Qty],
          sum(Case DATENAME(month,T2.DocDate) when 'March' then T1.Quantity   else 0 end) as [March Qty],
          sum(Case DATENAME(month,T2.DocDate) when 'April' then T1.Quantity   else 0 end) as [April Qty],
          sum(Case DATENAME(month,T2.DocDate) when 'May' then T1.Quantity   else 0 end) as [May Qty],
          sum(Case DATENAME(month,T2.DocDate) when 'June' then T1.Quantity   else 0 end) as [June Qty],
          sum(Case DATENAME(month,T2.DocDate) when 'July' then T1.Quantity   else 0 end) as [July Qty],
          sum(Case DATENAME(month,T2.DocDate) when 'September' then T1.Quantity   else 0 end) as [September Qty],
          sum(Case DATENAME(month,T2.DocDate) when 'October' then T1.Quantity   else 0 end) as [October Qty],
          sum(Case DATENAME(month,T2.DocDate) when 'November' then T1.Quantity   else 0 end) as [November Qty],
          sum(Case DATENAME(month,T2.DocDate) when 'December' then T1.Quantity   else 0 end) as [December Qty]
FROM [dbo].[OITM]  T0
      INNER JOIN INV1 T1 ON T0.ItemCode = T1.ItemCode
      INNER JOIN OINV T2 ON T1.DocEntry = T2.DocEntry
WHERE DATENAME(YEAR ,T1.DocDate )=@Year
GROUP BY DATENAME(month,T1.DocDate ),T0.[ItemCode], T0.[ItemName], T0.[OnHand]
Change @year=2010 to 2011 or 2009.It will show the analysis for particular year set.
Thanks,
