Thanks Nagarajan for the tip.
This is my desired Query.
SELECT T0.[ItemCode], T2.[ItemName], T4.[ItmsGrpNam],
T0.[CardCode], T1.[CardName], T5.[GroupName], T3.[SlpName], T0.[LINENUM],
T0.[Price], T0.[Currency], T6.Price, T0.[Discount], T0.[ListNum] as 'Item Price
List',T1.[ListNum] as 'Customer Price List', T0.[FromDate], T0.[ToDate]
FROM SPP1 T0 inner join OCRD T1 on T0.CardCode=T1.CardCode INNER JOIN OITM T2
ON T0.ItemCode = T2.ItemCode INNER JOIN OSLP T3 ON T1.SlpCode = T3.SlpCode
INNER JOIN OITB T4 ON T2.ItmsGrpCod = T4.ItmsGrpCod INNER JOIN OCRG T5 ON
T1.GroupCode = T5.GroupCode left JOIN ITM1 T6 ON T2.ItemCode = T6.ItemCode and
T6.[PriceList] = T0.[ListNum]
