How to avoid grouping by date with dates as incoming parameters?

Question

Hello, I have the following Query from SAP Business One set as DataSource:
SELECT  T1.SlpName as 'Vendor', convert(varchar(12), T0.[U_ER_PROV])as 'City', T0.[CardCode] as 'Client Code', T3.CardName as 'Client Name', T0.DocDate as 'Date', T2.ItemCode, T4.ItemName as 'Reference Description', sum (T2.Quantity) as 'Toal Units per Reference',
avg (T2.Price)as 'Average Price', sum(T2.LineTotal) as 'Total'
FROM ODLN T0
INNER JOIN OSLP T1
ON T0.SlpCode = T1.SlpCode
INNER JOIN DLN1 T2
ON T0.DocEntry = T2.DocEntry
INNER JOIN OCRD T3
ON T0.CardCode = T3.CardCode
INNER JOIN OITM T4
ON T2.ItemCode = T4.ItemCode
group by  T1.SlpName, convert(varchar(12), T0.[U_ER_PROV]), T0.[CardCode], T4.ItemName, T0.DocDate, T2.ItemCode, T3.CardName
order by  T1.SlpName, convert(varchar(12), T0.[U_ER_PROV]), T0.CardCode, T0.DocDate, T2.ItemCode
What I´d like to do is, grouping in Crystal Reports, the result of this query by Item Code, not by date. The problem I have is that I need users introduce "from date" to "end date" as incoming paramater.
The way I am running it, for example  I have some results like:
date                         Item Code               Total
01/01/2009               4646_R2                  120 u20AC
10/01/2009               4646_R2                  34 u20AC
And I´d like to take something like this:
Item code                       Total
4646_R2                         154 u20AC
Not grouping by date ......
Is there any way to do this using this query in Crystal Reports?
Thanks very much for your time.
