Service Group configuration, also called Smart Configuration, is a concept introduced to support lifecycle management connectivity for SAP applications. Using Service Group configuration, the applications created in Web Dynpro, Visual Composer, or Portal can be configured in a single location. The previous effort required to configure individual runtime settings by destinations is avoided by configuring the runtime settings of the applications created in different frameworks at one time using Service Group configuration features.

Note Note

Service Group currently supports the consumption of Web services only.

End of the note.

The Web services can be consumed from three sources:

  • Web Service Description Language (WSDL): A direct Uniform Resource Locator (URL) to connect to a specific Web service.

  • Web Services Inspection Language (WSIL): Provides an XML format for assisting in the inspection of a site for available services and a set of rules for how inspection-related information should be made available for consumption. It is the aggregation of Web services defined in a special XML file with a WSIL template.

  • Services Registry: The SAP solution for the aggregation of Web services with a capability to categorize them according to classifications and enable the user to search, browse, and consume the services. It consists of all the services that the developers need to develop applications stored in the Services Registry. Before you can start using the Services Registry, you must first configure the Universal Description, Discovery, and Integration (UDDI) server and set destinations to the UDDI server and the classification service.

Prerequisites

  • You have installed SAP NetWeaver Developer Studio 7.1.

  • You have created a Web service destination.
