Hi,
Try this:
/* SELECT FROM [dbo].[OINV] P1 */
/* WHERE */
DECLARE @Cust nvarchar
SET @Cust=/* P1.Cardcode */'[%0]'
SELECT ItemCode ,DocDate, Dscription, FrgnName,Available, Price
    FROM (
        SELECT T1.ItemCode ,T1.Dscription, T2.frgnName,T2.OnHand-T2.IsCommited as 'Available',T0.DocDate , T1.Price,
  Rank() over (Partition BY T1.ItemCode ORDER BY T0.DocDate DESC ) AS Rank
        FROM OINV T0 INNER JOIN INV1 T1 ON T0.DocEntry = T1.DocEntry
        INNER JOIN OITM T2 ON T1.itemcode = T2.itemcode
          WHERE T0.Cardcode = @cust
        ) rs WHERE Rank <= 1
