Learn how to combine SAP NetWeaver Business Process Management (SAP NetWeaver BPM) and the Advanced Adapter Engine Extended (AEX — the new Java-only deployment option of SAP NetWeaver Process Integration) for implementing highly sophisticated integration processes. In addition, get an understanding about how integration patterns can be modeled using the business process model and notation (BPMN) standard. Discover the developments on the AEX before stepping through the implementation details on the BPM side.
Key Concept
Integration patterns explain proven techniques to solve recurring integration problems. They address issues that integration experts face in their day-to-day work. Business process model and notation (BPMN) can be used as a pattern language for system-centric processes, resulting in a standards-based and widely adopted means for communicating solutions.

Starting with SAP NetWeaver Process Integration (SAP NetWeaver PI) 7.3, SAP offers a completely new Java-only deployment option for its integration software. The Advanced Adapter Engine Extended (AEX) allows the installation of an autonomous integration middleware stack that is independent from the cost-intensive double-stack environment of SAP NetWeaver PI (Java and ABAP). As outlined in Elke Doering and Peter Gutsche’s SAPexperts article “SAP NetWeaver 7.3: AEX: A New Installation Option for SAP NetWeaver PI,” this comes with some restrictions. One major drawback is the missing support of integration processes (also known as cross-component business process management [ccBPM] processes), as the ccBPM functionality is completely handled on the ABAP stack.

However, integration processes play an essential role for companies using SAP NetWeaver PI, so it is important to provide a similar functionality for Java as well. You can achieve this by combining SAP NetWeaver Business Process Management (SAP NetWeaver BPM) and AEX. I’ll explain in detail how this collaboration can be achieved and how BPMN-based integration patterns speed up your integration efforts. Integration experts, developers, and architects can benefit from this approach as they will get working implementations for classical integration challenges that are immediately usable in their projects. Let’s start by talking about integration processes in more detail.

Prof. Dr. Volker Stiehl studied computer science at the Friedrich-Alexander-University of Erlangen-Nuremberg. After 12 years as a developer and senior system architect at Siemens, he joined SAP in 2004. As chief product expert, Volker was responsible for the success of the products SAP Process Orchestration, SAP Process Integration, and SAP HANA Cloud Integration (now SAP HANA Cloud Platform, integration service). He left SAP in 2016 and accepted a position as professor at the Ingolstadt Technical University of Applied Sciences where he is currently teaching business information systems. In September 2011, Volker received his Ph.D. degree from the University of Technology Darmstadt. His thesis was on the systematic design and implementation of applications using BPMN. Volker is also the author of Process-Driven Applications with BPMN as well as the co-author of SAP HANA Cloud Integration and a regular speaker at various national and international conferences.
