The event scheduler processes an event if the event is defined in the system.

For example, if a system (System 1) receives an event from another system (System 2), the event scheduler of System 1 processes the event only if it is defined in System 1. That event does not need to be defined in System 2 (the sending system).

You define an event by assigning a name (EVENTID) to it. When defining an event, you do not define the event arguments.
