NULLS are treated as high priority when assigned row numbers with in a group - forum topic by bikky6

Hi
 
I have the below table and I am trying to assign rownumber and need to get row_number=1 for the values.But theere are NULL's in the group  where they are being treated high priority and 1 is assigned to it.
 
Let me know if there is any option to treat this.
CT KVB1(EMPNO INTEGER,ENAME VARCHAR(10),DNO INTEGER,DNAME VARCHAR(10));
INS INTO KVB1 VALUES(1,'A',10,NULL);
INS INTO KVB1 VALUES(1,'A',NULL,NULL);
INS INTO KVB1 VALUES(2,'B',10,NULL);
INS INTO KVB1 VALUES(3,'C',NULL,NULL);

SEL EMPNO,ENAME,DNO, ROW_NUMBER() OVER(PARTITION BY EMPNO,ENAME ORDER BY DNAME DESC) RN FROM KVB1

Rownumber 1 is being assigned to NULL values.But in Teradata NULLS are treated as least.
Or is there any option in Teradata to treat the NULLS at last
