Inventory Report in Query.

Experts correct my code how to get an exact code.

Thanks.

Declare @FromDate Datetime
Declare @ToDate Datetime
Declare @Whse nvarchar(10)
select @FromDate = min(S0.Docdate) from dbo.OINM S0 where S0.Docdate >='[%0]'

select @Whse = Max(s2.Warehouse) from dbo.OINM S2 Where S2.Warehouse = '[%2]'

Select @Whse as 'Warehouse', a.Itemcode, max(a.Dscription) as ItemName,sum(b.OpeningBalance) as OpeningBalance, sum(sum(a.Del)-sum(a.Ret)) As Withdrawal.
