Query gives error

Question

Hi All,
I am encountering such problems time and again while running such queries in Query wizard : following is my query and it runs if I dont add the 'where' clause.
SELECT T0.[CardName] as 'Customer Name' , T0.[NumAtCard], T0.[DocNum], T1.[ItemCode], T1.[Dscription], T1.[Quantity], T1.[Price], T0.[DocTotal], T1.[StockPrice] as 'Final ItemCost',
   convert(varchar,(select sum(isnull(T2.stockprice * T2.Quantity,0)) from dbo.DLN1 T2 where T1.docentry = T2.docentry))  as [Total Item Cost],
(T1.[Quantity] * T1.[Price])-(T1.[StockPrice] * T1.[Quantity])  as 'Profit on Sale of Item', T1.BaseRef as 'Sales Order No.'  FROM dbo.ODLN T0  INNER JOIN dbo.DLN1 T1 ON T0.DocEntry = T1.DocEntry
if at the end , I add
where T1.BaseRef  = [%0]
or
where T1.BaseRef  = Isnull([%0], T1.Baseref)
it gives me the error 'Must specify the table to select from'.
what is that I am doing wrong?
thanks,
Binita

Hi Binita,
Apparently it's because you mentioned T1 in the subquery,
   convert(varchar,(select sum(isnull(T2.stockprice * T2.Quantity,0)) from dbo.DLN1 T2 where T1.docentry = T2.docentry))  as [Total Item Cost],
If you omit the subquery then the query will run with the condition WHERE T1.BaseRef = '[%0]'.
I think Query Generator in SAP B1 has problem in recognizing parameters that refer to tables which are mentioned in subquery.
You need to declare the parameters as variables outside the query and then use the variables in the conditions.
You can use Gordon's query anyway.
