Hi Dushanth,

You create a Web service so that users can access the available functions, such as an RFC-enabled function module, function group, BAPI, or XI message, even those stored in a different system.

Two roles are provided for creating Web services:

● Web Service Developer

The Web service developer defines the Web service at design time. He or she knows the application logic as well as the resulting conditions for the communication type (for example, stateless/stateful), and the required security level. He or she defines these properties at an abstract level. Specific details, such as the transport binding or security concept to be used, are defined only later during the Web service configuration.

● Web Service Configurator

The Web service configurator defines the behavior of the Web service at runtime. He or she knows the system landscape and the technical requirements of the application server where the Web service is to be called. On the basis of the abstract definition of the Web service, the configurator can decide during configuration which specific attributes should be assigned to the features defined at design time.

Prerequisites

To create or consume Web services, you need the authorizations associated with the role SAP_BC_WEBSERVICE_ADMIN. You must add the authorization S_ICF_ADMIN (authorization for the Internet Communication Framework) to your profile. You use the authorization S_SERVICE for starting external services.

Procedure

Um einen ...

● To create a Web service for a function module, function group, BAPI, or XI message interface with a predefined feature profile, use the Web Service Creation Wizard.

● To specify the features of the Web service yourself, follow the procedure described in Creating a Virtual Interface.

You can also create Web services using the Web Service Creation Wizard, and then change the virtual interface and Web service definition in the Object Navigator (SE80), by choosing Enterprise Services ® Web Service Library.

Hi Dushanth Reddy,

webservice is like a remote procedure call over the internet using SOAP protocal. You will have a request structure and a corresponding response structure.

the caller initiates the call, without knowing anything about where there the data is coming, which systems to connect etc, all the user needs to know is the invoke the webservice and the webservice implementation returns the data as response structure.
