This documentation is aimed at system and network administrators. You will learn about the configurations necessary for SAP systems to be able to communicate with each other and with external programs and systems.
If you want to connect an SAP Web Application Server System to an external system, SAP recommends you use the standalone gateway 4.6D.
This documentation describes the SAP Gateway with regard to how to use, configure, and monitor it.
For information on RFC-based programming, refer to the following documentation: Remote Communications.
