This is the heart of the SAP system. In the classic three-tier model, this would be the logic or control layer. One or more application servers host the necessary services for the various applications on this layer. These application servers provide all the services required by the SAP applications.

The core of the three-layer model is the application layer. This consists of one or more application servers and a message server. Companies use the application server to provide services for the operation of applications in SAP. The message server serves as an "intermediary" between the applications and services, for example, by controlling communication between the individual application servers and determining the load on the application servers. Furthermore, the data is prepared for the user in the application view so that the user can call up the data visually in the presentation layer. At the same time, the user data is forwarded to the database.
The presentation layer is used to visualize the applications and data for the user. The presentation is done with the help of a graphical user interface (GUI). Furthermore, the presentation view consists of several modules, which are also summarized as SAP GUI. SAP Fiori is the presentation layer of the next generation and is therefore particularly user-friendly.
