ABAP Channels provide an event-based communication using messages between application servers and with the Internet.

This document outlines the enabling technology for efficient push-messaging between ABAP and UI sessions, including the respective user agents. It mainly consists of two basic elements:

  • A push channel, enabling bi-directional communication with user agents (e.g. via the integration of WebSockets) in the SAP NetWeaver Application Server.

  • A publish/subscribe infrastructure (messaging channel) for the exchange of messages between different user sessions residing on different SAP NetWeaver Application Servers.

Besides character and byte strings, also the SAP-specific Push Channel Protocol (PCP) can be used as message format for ABAP Channels..

Note For more information see also the ABAP Keyword Documentation ABAP Channels (ABAP - Reference → Data Interfaces and Communication Interfaces → ABAP Channels).
