No Trap Parser Defined on SNMP trap

No Trap Parser Defined on SNMP trap

I am using OpManager v12 free edition.
I had already add the trap processor by loading from mib file but don't know why the recevied SNMP trap still saying "No Trap Parser Defined".
Would like to know if I had missed any settings?
