Introduction to ABAP Channels

Overview

ABAP Channels infrastructure was delivered with SAP NetWeaver AS ABAP 7.40 support package 2 (SP2) for simple tests and prototyping and released with 7.40 support package 5 (SP5).

The basic idea of the ABAP Channels (see Figure 1) is the native support of interactive and collaborative scenarios based on event-driven architecture. The scope of ABAP Channels consists of the following communication channels:
  • ABAP Push Channel for bi-directional communication with user agents via WebSockets in ABAP. In the Figure 1 the documents tagged with letter "P" mark the ABAP Push Channel communication paths.
  • Publish/subscribe infrastructure for exchange of messages between either user sessions (Session C => Session A) or user session and user agents
