Build resilient, long-running background processes in SAP S/4HANA without dialog timeouts. Generate ABAP Cloud Daemons (cl_abap_daemon), Push Channel Protocol (PCP) message dispatchers, and automated recovery loops.
Complete blueprints for Daemons, Application Jobs, and RAP extensibility in The SAP Clean Core & ABAP Cloud Handbook.
Unlike standard dialog or RFC processes bound by rdisp/max_wprun_time, ABAP Daemons are specialized background sessions designed to run continuously for weeks.
Daemons communicate with other application server sessions asynchronously using typed, structured PCP messages containing key-value metadata and text/binary bodies.
Built purely on released API cl_abap_daemon_ext_base with strict Language Version 5 (ABAP Cloud) compatibility. Fully operational on S/4HANA Cloud and BTP ABAP Environment.
