Definition

The delivery of events from the event queue is performed in several steps. A background job reads a number of events from the queue and starts event delivery for each of these events. In the event delivery, the receivers entered for each event are established and started in succession.

The type of event delivery determines how the events are forwarded to the relevant receivers from the event queue. The following options can currently be set:

  • Synchronous
    • The events are read from the event queue. Both the event delivery and the starting of the receivers are processed synchronously (receivers are started via RFC).
  • Synchonous delivery with asynchronous starting of receivers (tRFC)
    • Delivery is called synchronously for the events read from the event queue. However, the receivers established are not started immediately, but are marked for asynchronous delivery in a separate LUW (Logical Unit of Work) instead.

The event receivers are not started until the next explicit COMMIT WORK. A new work process is opened. The instruction "COMMIT WORK" is taken over by the background job of the event queue after all event deliveries. This means that all event receivers marked for starting are called in a separate LUW.

  • Asynchonous event delivery (aRFC)
    • The events read from the event queue are delivered asynchronously in parallel. Within each event delivery the receivers are started synchronously. A specific server group can be chosen for execution of the asynchronous delivery. The background job of the event queue waits after all the event delivery calls until all the asynchronously started calls are finished.
