reprocess event message

Hi all experts,

Is there a way to reprocess already processed event message in EM? Scenario is, I receive an event-->rule set process-->in one of the ruleset activity i reset the event status using EE_RESET due to some update failure in external system.

Now I may not get the event message again from external party, but I need to reprocess this message again after sometime as i know that update failure won't occur in external system. This will set my EE status to green.

Thanks in advance,

Anu
