ABAP Connectivity

Moderator of this WIKI section is
Frank Mueller.

Welcome to the ABAP Connectivity Wiki space. Starting with this page you can find any kind of topics related to communication from an to an ABAP Server. In particular, the ABAP Connectivity Wiki covers the areas of Remote Function Call (RFC), Internet Communication Framework (ICF), ABAP Channels (AC), ABAP Connectors (SAP Java Connector, SAP Java Resource Adapter, (NW) RFC SDK, SAP Business Connector, SAP .Net Connector, SAP ABAP Connector) and Web Services ABAP. In other words: it is dedicated to all core technologies that connect an ABAP server to any other system (ABAP or non-ABAP) directly or over the internet. On this page you will find a lot of links to different information sources (like SAP documentation, SDN articles and blogs, related books, trainings) for each technology component. And - of course - you will find all the material added by our contributors.This main page is not intended for public changes. Feel free to add you content to one of the child pages below or create your own child page.
