Creating Service Interface DefinitionsLocate this document in the navigation structure


You create service interface definitions or WSDL files to use them in your business process model and so you can execute it. You define operations for the service interface definitions you use in your process. The operation is an abstract description of an action supported by the service.

After you have created the necessary WSDL files, you can include them in a Service Group to be able to easily configure them when you deploy your process. For more information, see Working with Service Groups .


You have opened the Process Development perspective in the SAP NetWeaver Developer Studio and have expanded your project in the Project Explorer view.
