What are the steps you need to take to call an Web Service

Provider builds and defines the service in WSDL

Provider registers the service in UDDI

User finds the service by searching UDDI registry

Generate the proxy class from the WSDL

All SAP applications can expose services

You can develop a service in any release

Release 4.6 and older require additional components to expose Web services. This can be e.g. a SAP Web Application Server or the SAP Exchange Infrastructure

The service you have developed does not change during an upgrade to a higher release, but automatically becomes available as a Web service
