The core of SAP Basis is the application layer with one or more application servers and a message server. The message server is used for communication between the application servers and transmits jobs between them. The application layer communicates with the database layer on the one hand and the presentation layer on the other. The applications on the application server request the required data from the database, process it and prepare it for the user, who displays it in his Graphical User Interface (GUI) via the presentation layer. Conversely, the application server passes information that the user enters via the GUI on to the database.

Note that a change only takes effect when the instance is restarted!
