Temporary Table In SAP Query - Does not Work?

Question

DECLARE @date DATE
DECLARE @delrows INT
DECLARE @delquan INT
DECLARE @a INT
DECLARE @recrows INT
DECLARE @recquan INT
SET @a=0
IF OBJECT_ID('tempdb..##tab) IS NOT NULL DROP TABLE ##tab
CREATE TABLE ##tab
[Date] date,
[Delivery Rows] varchar(40),
[Delivery Total Units] varchar(40),
[Receipts Rows] varchar(40),
[Receipts Total Units] varchar(40),
WHILE @a!=7
     BEGIN
     SET @date=DATEADD(day,-@a, getdate())
     SELECT @delrows=ISNULL(COUNT(DLN1.[LineNum]),0), @delquan=ISNULL(SUM(DLN1.[Quantity]),0)
     FROM ODLN
     INNER JOIN DLN1 ON ODLN.[DocEntry]=DLN1.[DocEntry]
     WHERE ODLN.[CreateDate] = @date
     SELECT @recrows=ISNULL(COUNT(PCH1.[LineNum]),0) , @recquan=ISNULL(SUM(PCH1.[Quantity]),0)
     FROM OPCH
     INNER JOIN PCH1 ON OPCH.[DocEntry]=PCH1.[DocEntry]
     WHERE OPCH.[DocDate]=@date
     SET @a=@a+1
          INSERT INTO ##tab VALUES(@date,@delrows,@delquan,@recrows,@recquan)
END
SELECT * FROM ##tab
{/code}
Can anyone explain why this query does not work in SAP? It works fine on SQL but gives me this message in SAP:
1). [Microsoft][SQL Server Native Client 10.0][SQL Server]Incorrect syntax near ')'.
2). [Microsoft][SQL Server Native Client 10.0][SQL Server]Statement 'Service Contracts' (OCTR) (s) could not be prepared.

Chris,
There are several areas in your code which needed changes. 
1. On the field name for your temp table you had spaces.
2. The SAP table name ODLN, OPCH, PCH1 had to be fully referenced like
[dbo].[ODLN]
3. You really need not have ## in front of your temp table, it could just be #
The select at the end is actually what causes the most problem as for some reason from within SAP it does not produce the result.  I would suggest you put the whole code into a Stored Procedure and call the SP from SAP.  Corrected SQL below.  If you remove the Select line at the end the query would work with in SAP, but keep it give give you an error. SP is the best option for this.
DECLARE @date DATE
DECLARE @delrows INT
DECLARE @delquan INT
DECLARE @a INT
DECLARE @recrows INT
DECLARE @recquan INT
SET @a=0
IF object_id('tempdb..#tab') IS NOT NULL
BEGIN
   DROP TABLE #tab
END
CREATE TABLE #tab
[Date] date,
DeliveryRows varchar(40),
DeliveryTotalUnits varchar(40),
ReceiptsRows varchar(40),
ReceiptsTotalUnits varchar(40),
WHILE @a!=7
BEGIN
SET @date=DATEADD(day,-@a, getdate())
SELECT @delrows=ISNULL(COUNT(DLN1.LineNum),0), @delquan=ISNULL(SUM(DLN1.Quantity),0)
FROM [dbo].[ODLN]
INNER JOIN DLN1 ON [dbo].[ODLN].DocEntry=DLN1.DocEntry
WHERE [dbo].[ODLN].CreateDate = @date
SELECT @recrows=ISNULL(COUNT([dbo].[PCH1].LineNum),0) , @recquan=ISNULL(SUM([dbo].[PCH1].Quantity),0)
FROM [dbo].[OPCH]
INNER JOIN [dbo].[PCH1] ON [dbo].[OPCH].DocEntry=[dbo].[PCH1].DocEntry
WHERE [dbo].[OPCH].DocDate=@date
SET @a=@a+1
INSERT INTO #tab VALUES(@date,@delrows,@delquan,@recrows,@recquan)
END
SELECT * FROM #tab
