Hola todos.
Estoy tratando de de realizar una consulta sobre el movimiento de articulos por periodo por almacen, ya tengo el valor inicial, tengo una entrada, una salida y el inventario final, pero no he podido sacar el campo donde esta el costo del item, será que me pueden ayudar con este asunsto, les agradesco la atención prestada.

este es el codigo que me genera la consulta donde obtengo los campos que he mensionado:

Declare @FromDate Datetime
Declare @ToDate Datetime
Declare @Whse nvarchar(10)

Set @FromDate = (Select min(S0.Docdate) from dbo.OINM S0 where S0.Docdate >='[%0]')
Set @ToDate = (Select max(S1.Docdate) from dbo.OINM s1 where S1.Docdate <='[%1]')
Set @Whse = (Select Max(s2.Warehouse) from dbo.OINM S2 Where S2.Warehouse = '[%2]')


Select
@Whse as 'Warehouse',
a.Itemcode,
max(a.Dscription) as ItemName,
sum(a.OpeningBalance) as OpeningBalance,
sum(a.INq) as 'IN',
sum(a.OUT) as OUT,
((sum(a.OpeningBalance) + sum(a.INq)) - Sum(a.OUT)) as Closing
,(Select i.InvntryUom from OITM i where i.ItemCode=a.Itemcode) as UOM
from(
Select
N1.Warehouse,
N1.Itemcode,
N1.Dscription,
(sum(N1.inqty)-sum(n1.outqty)) as OpeningBalance,
0 as INq,
0 as OUT

Where
N1.DocDate < @FromDate
and N1.Warehouse = @Whse
