                      CASE WHEN B.itemcode = F .itemcode and A.CardCode = G.CardCode and A.Slpcode = F.Slpcode THEN B.quantity - F .quantity ELSE B.quantity END AS Quantity,
                      CASE WHEN B.itemcode = F .itemcode and  A.CardCode = G.CardCode and A.slpcode = F.slpcode THEN B.price - F .price ELSE B.price END AS Price, B.DiscPrcnt,
                      CASE WHEN B.itemcode = F .itemcode and A.CardCode = G.CardCode THEN B.linetotal - F .linetotal ELSE B.linetotal END AS Amount, B.VatPrcnt,F.ItemCode,E.Itemcode,D.Itemcode,C.Itemcode

Maybe this will help you further?
SELECT A.CardCode, DocNum AS 'Ord.No', CONVERT(varchar, A.DocDate, 3) AS 'Date', B.Dscription AS 'Item Name', B.ItemCode AS 'Item Code'
, SUM(B.quantity - D.quantity) AS 'Quantity'
, SUM(B.price - D.price) AS 'Price'
, SUM(B.LineTotal - D.LineTotal) AS 'Amount'
      FROM ORDR A
INNER JOIN RDR1 B ON (A.DocEntry = B.DocEntry)
LEFT JOIN DLN1 C ON (B.DocEntry = C.BaseEntry AND B.LineNum = C.BaseLine)
LEFT JOIN RDN1 D ON (C.DocEntry = D.BaseEntry AND C.LineNum = D.BaseLine)
WHERE (A.DocDate >= '20090925') AND (A.DocDate <= '20090925') AND (A.CardName = 'SHASUN CHEMICAL AND DRUGS')
GROUP BY A.CardCode, A.DocNum, A.DocDate, B.Itemcode, B.Dscription
ORDER BY 'Date'
