SAP NetWeaver Event Enablement Add-on
Event-driven Architecture with SAP ERP Systems

Introduction to Event Messaging
SAP TechEd 2018 Keynote
Story Flow:
§
A production order in S/4HANA gets updated
§
This triggers the sending of an event to the SAP
Cloud Platform into a queue from SAP Cloud
Platform Enterprise Messaging
§
A function (SAP Cloud Platform Extension
Factory, serverless runtime) is subscribed to the
queue and directly reads from various systems
additional data. Then the functions sends an
update via twitter

SAP TechEd 2020 Keynote
Similar Scenario as shown in the 2018
Keynote, but now focusing on SAP ECC.
For SAP ECC customers SAP released a new
Add-On (SAP NetWeaver Add-On for Event
Enablement).
Customers can start with extensions on SAP
Cloud Platform today – no need to wait for SAP
S/4HANA – simply leverage Events and OData
Services which are provided by SAP Gateway.

SAP NetWeaver® Event Enablement Add-on
Benefits of event-driven architectures
Event-Driven Architectures
§
§
§
Benefits
Distributed asynchronous architecture
pattern used to produce highly scalable
applications.
§
Decouples communication
§
Removes idle downtimes
Made up of highly decoupled, singlepurpose event processing components
that asynchronously receive and process
events.
§
Enables responsive applications that
react to events in other
systems/applications
§
Permits events to trigger functions (as
a service) in response to execute
defined business logic
§
Facilitates pay-per-use consumption
costs by removing “always on”
A key element of event notification is that the
source system doesn't really care much
about the response.

SAP NetWeaver® Event Enablement Add-on
When should you consider Event Messaging with SAP Systems?
New Connectivity:
e.g. connect non-SAP systems, SaaS/PaaS systems and platforms, cloud applications, mobile
platforms, data lakes etc. to on-prem SAP systems
Performance & Scalability:
e.g. switch batch interfaces to event-based/real-time interfaces, allow micro-batching/partitioning
and parallel data loads for high-volume batch interfaces, redesign high-frequency / high-load SAP
standard interfaces to event-based, enable 1:n connectivity without middleware
Security & API Management:
e.g. build custom interfaces, to benefit from its uniform approach for all kind of external
connectivity, including central monitoring, or replace (specific) 1:1 interfaces with event-busarchitecture

Events – where could they be implemented?
Middleware centric approach:
§ Custom API developments required
§ iPaaS or middleware required
§ No direct data access
§ Typically 1:1 connectivity
§ Hardly re-usable
