Understanding Event-driven Architecture in SAP S/4HANA: Notification Events vs. Full State Events

Event-driven architecture (EDA) is a software architecture paradigm that enables components to react to state changes or occurrences in real-time through asynchronous communication. In SAP S/4HANA, this paradigm shift is reflected in the concept of business events. Standard business events are notification events that inform subscribers about the occurrence of an event, while full state events include the entire current state of a business object. The choice between these two types of events depends on the specific use case and the desired level of data dependency, coupling, and failure tolerance.
