Sales Analysis query per item group summarized per BP Group

Question

Dear experts,
My client is requiring me to create a query that when i select a certain item group it returns a sum/total of sold items in that group per BP group
format:
parameter: Item Group A
BP Group A    1,000
BP Group B    2,000
BP Group C   1,000
I have managed to get total sales per BP Group but i cant seem to figure how to break it down per Item Group
here is my query:
SELECT T2.[GroupCode], SUM(ISNULL(T0.Debit,0) - ISNULL(T0.Credit,0)) as "Amount(LC)" FROM JDT1 T0  INNER JOIN OJDT T1 ON T0.TransId = T1.TransId and T0.TransType IN (13,14)
INNER JOIN OCRD T2 ON T2.CardCode = T0.ShortName
WHERE T1.[RefDate]  BETWEEN [%0] and [%1]
GROUP BY T2.[GroupCode]
how can I link Item Groups to JDT1?

Hi Carlo
Try This
SELECT t5.ItmsGrpNam AS ItemGroup,
   t7.GroupName AS BPGroup,
   SUM(ISNULL(T0.Debit,0) - ISNULL(T0.Credit,0)) AS "Amount(LC)"
FROM JDT1 T0
INNER  JOIN OINV T1 ON T0.transid = T1.transid
LEFT OUTER JOIN INV1 T3 ON T1.docentry = T3.docentry
LEFT OUTER JOIN oitm T4 ON t4.itemcode = T3.itemcode
LEFT OUTER JOIN oitb T5 ON T4.ItmsGrpCod = T5.ItmsGrpCod
INNER  JOIN ocrd T6 ON T0.ShortName = T6.CardCode
INNER JOIN OCRG T7 ON t7.GroupCode=t6.GroupCode
WHERE T1.DocDate BETWEEN [%0] AND [%1]
GROUP BY t5.ItmsGrpNam,
   t7.GroupName
