Not in the same table, I hope!
Within a single table, you should use *either* read-write,
*or* read-create,  but you can't mix the two.
   (See RFC 2578, section 7.3, paragraph 4)

read-create means that it makes sense to try and create
a new row in the table.   read-write means that it doesn't.

You can validly use SET with an existing instance of a
read-write object,  but you can't try to create a new one.

See RFC2578, section 7.3 for details.
Or any good book on SNMP & MIBs should cover this.
