OBIEE Remove Default Order By

Question

Hi,
My users have a specific request in a OBIEE report. The report is based on 2 tables connected directly to the transaction system in AS400/DB2. The reason is the report must show real-time data. So far so good, OBIEE is able to connect and show the live data without caching the results (disabled the cache for these tables).
The problem is they need to see the rows in a report in a chronological order (the newest row inserted on DB2 in the bottom). I don't have any cronological column in the table to apply the OBIEE sort. OBIEE Admin Tools shows the desired order when I click on "view data" option in the Physical Table. The records are being displayed exactly as I need.
When I created the report on OBI Presentation, I can see on Advanced Tab that it includes a default "Order By" clause in the SQL Statement. I was able to remove the distinct by disabling the database feature DISTINCT_SUPPORTED in the rpd file.
Also, I tried to comment the //SORT_TYPE = "binary"; in the NQSConfig.ini but it didn't solve the problem. Tried to use a logical ROWNUM column but AS400/DB2 does not support this type of column.
How can I get rid of the "order by" clause in a OBIEE report? I must have to disable this default order on OBIEE to bring the default table order (as the rows were inserted).
I appreciate your help,
Thanks.

Hi Saichand,
Thanks for your answers.
I've uncked the ORDERBY_SUPPORTED feature, restarted BI Server and Presentation. My report does not have any column flagged to sort, even thought it still applying an order by clause in the SQL Statement. I went to the Advanced tab on Answers I can see the order clause in the SQL statement and this is the log generated by the query:

It seems that OBIEE did not remove the "order by" as expected.
Can you please let me know how to force OBIEE to do not use the order by clause?
Thanks,
