An event in SAP is defined as an occurrence of a status change in an object. The event is created when the relevant status change occurs. You or SAP must implement event creation.

An event is created from a specific application program (the event creator) and then "published" system-wide. An unlimited number of receivers can respond to the event with their own "response mechanisms". An event is usually defined as a component of an object type.

SAP "pseudo events" are events that are not processed by the SAP Event manager, but are called from an ABAP program or Remote Function call (using the Destination parameter).
