Modeling External Services 

Purpose

You can use remote function call (RFC) or Web services (WS) to permit accessibility of data from an external source such as SAP Systems or a URL. You cannot change imported information; however, additional information can be added to certain fields.

Prerequisites

You have opened the Composite Application Services (CAS) perspective in SAP NetWeaver Developer Studio.

Process Flow

       1.      You import either a remote function call (RFC) or a Web service (WS). See:

○     Importing External RFC Services

○     Importing External Web Services

       2.      You edit the external service (see Editing External Services).

       3.      You integrate the service in your application. See:

○     Encapsulating External Services as Entity Services

○     Encapsulating External Services as Application Services
