To consume Web services that are running on a provider system, you have to establish a connection from your client system to this provider system. When you create the connection, you specify the policies of the communication between the systems. These policies apply only to the communication between the systems and do not apply to the concrete services on these systems. You define the policies in communication profiles and refer to them in the system connection. At a later stage, the business administrator uses the system connections to configure groups of consumer proxies that consume Web services on the configured provider systems.

For more information, see Connection to Provider Systems

At a later stage, the business administrator assigns these provider systems to one or more Service Groups, and thus creates a runtime configuration for the applications that consume the respective service references. When the business administrator assigns a provider system that uses WS connectivity to a deployed Service Group, the system creates configuration entities (logical ports) that have the specific configuration settings of the connection. The configuration of Service Groups with RFC provider systems results in the creation of an RFC destination to the system which can be used for invocation of the remote function module.
