You need to find your MAX values in a subquery, then use those results to join to your main table to retrieve the columns.

        INNER JOIN (SELECT ItemNumber, MAX(OrderFileId) AS MaxOrderId
                        FROM YourTable
                        GROUP BY ItemNumber) q
            ON t.ItemNumber = q.ItemNumber
                AND t.OrderFileId = q.MaxOrderId
