Case 1: Event Handler is Active and Not Archived
In this standard case, SAP Event Management saved an event handler in the database and marked it as active using the indicator /SAPTRX/EH_ACTIVE Event Handler Is Active. You can send event messages for this event handler. SAP Event Management processes these event messages depending on your Customizing settings. The system does not archive the event handler.
Case 2: Event Handler is Inactive and Not Archived
In this case, SAP Event Management saved an event handler in the database but the event handler is inactive. This means the indicator /SAPTRX/EH_ACTIVE Event Handler Is Active is not set. In the standard case, you cannot send event
messages for this inactive event handler. SAP Event Management does not process these event messages. In Customizing for SAP Event Management, you can define criteria to allow the system to forward or process an event message for an event handler that has been set to Inactive on
the basis of a rule in the rule set. For more information, see Customizing for SAP Event Management under Event Messages, Status Queries, and Web Interface 
Define Criteria for Event Message Processing . The system
does not archive the event handler.
Case 3: Event Handler is Inactive and Logically Archived
In this case, SAP Event Management saved an event handler in the database, but the event handler is inactive. This means the indicator /SAPTRX/EH_ACTIVE Event Handler Is Active is not set. SAP Event Management also archived the event handler logically. This means the indicator /SAPTRX/EH_ARCHIVED Event Handler Archived is set and the archiving report has already been executed. However, the event handler still physically exists in the database. SAP Event Management does not process event messages that you send for the logically archived event handler.
Case 4: Event Handler is Inactive and Archived
In this case, SAP Event Management saved an event handler in the database, but the event handler is inactive. This means the indicator /SAPTRX/EH_ACTIVE Event Handler Is Active is not set. SAP Event Management also archived the event handler. This means the indicator /SAPTRX/EH_ARCHIVED Event Handler Archived is set, and both the archiving and the deletion reports have already been executed. SAP Event Management deleted the event handler in the database. The application does not process event messages that you send for the archived event handler.
