Use
The linkage tables contain the assignment of
events to the event receivers interested in the events.The entries in the linkage tables must be made by the potential receiver of an event. This can be done using function modules provided or a maintenance transaction.

It is only necessary to maintain linkage tables manually if you use events within separate developments. If events are used exclusively within the SAP Business Workflow environment, all necessary entries (including transport) are made by the workflow system.
Integration
A distinction is made between
type linkage and instance linkage. They are contained in separate tables.Features
If there are appropriate entries in the linkage tables when the event is created, the event manager creates the linkage by calling the receiver function module.
If there are no appropriate entries in the linkage tables when the event is created, the event has no effect. Events are not buffered so that they can be produced at a later point in time.

It is, however, possible to temporarily store events for which a linkage is entered in the
The linkage between the creator and the receiver can be activated and deactivated by making a selection in the table (indicator Type linkage activated ) at definition time and even at runtime for a specific situation or customer.
