Hi,
Try:
SELECT T0.CardCode, T0.CardName, T2.SlpName, T4.ItmsGrpNam, MAX(T1.DocDate),T3.Discount
FROM dbo.OCRD T0
INNER JOIN OINV T1 ON T0.CardCode = T1.CardCode
INNER JOIN OSLP T2 ON T0.SlpCode = T2.SlpCode
INNER JOIN OSPG T3 ON T0.CardCode = T3.CardCode
INNER JOIN OITB T4 ON T4.ItmsGrpCod = T3.ObjKey
WHERE T2.SlpName =[%0\]
GROUP BY T0.CardCode, T0.CardName, T2.SlpName, T4.ItmsGrpNam, T3.Discount
order by T0.CardCode, T4.ItmsGrpNam
Thanks,
