Discover what you have to consider if you want to integrate a Web Dynpro component or a Web service for persisting data in your process. After you develop your UIs and your Web service, find out how to connect them with the respective process steps.
Key Concept


The development of a composite application is driven by new collaborative process ideas. Business process experts tend to develop these processes by using graphical modeling environments. In the past, there was always a break from this conceptual work to the real implementation due to the different tools that the business process experts and IT experts were using. This changed with the advent of the Business Process Modeling Notation (BPMN), which allows you to bridge the gap between business and IT.

BPMN is not executable out of the box. For each human activity, you need a user interface (UI) and for each automated activity, you need a service call. Using human activities created in my SAP Professional Journal article “Composite Designer and SAP NetWeaver Business Process Management Minimize Composite Application Development Efforts,” I will show you how to add Web Dynpro UIs for them and also how to add a Web service call for the automated activity.
