Remote Communications

Overview of Remote Communications

This section provides an overview of the remote communications involving SAP Systems.

ABAP Interfaces

This section describes the Remote Function Call interfaces provided for communication between SAP Systems and with external partners. It also contains a lot of useful information for the programmer of external systems who uses an RFC API.

External Interfaces

This section describes the communications interfaces provided for integrating external applications and SAP Systems.

If one of the communications partners does not support RFC, you must use the underlying CPI-C interfaces. For more information on CPI-C programming, see SAP Communication: Programmer’s Guide.
