Push Channel Protocol (PCP) Messaging in ABAP
An ABAP Daemon is a long-running, event-driven ABAP program that runs persistently in the background on the application server. Developers use it to handle asynchronous events and messages continuously without being tied to a user session. For example, an ABAP Daemon can be used to forward MQTT and AMC messages or to process incoming events as demonstrated in tutorials such as Create a Simple ABAP Daemon.

- Concept ABAP Messaging Channels An **ABAP Daemon** is a long-running, event-driven ABAP program that operates persistently in the background on the application server. Developers use it to handle asynchronous events and messages continuously without user interaction, for example to forward MQTT and AMC messages as they arrive. It is created by implementing a dedicated daemon class and can be managed through the ABAP Daemon framework.
