Creating a Service Definition
Use
You create a Web service so that users can access functions that were developed as an RFC-enabled function module, function group, BAPI, or XI message, and even functions located in a different system.
The Service Wizard enables you to create a service definition in a few steps. You can create Web services for RFC-enabled function modules, function groups, BAPIs, and service interfaces. You assign features that pertain, for example, to security or transport guarantees using configuration profiles.
Prerequisites
To create and bind Web services, you need the appropriate authorization.
