Design of the SAP landscape
Missing result documentation
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 implementation of a cross-sectional function will promote and safeguard the operation of the SAP systems that form the backbone of the company. By coordinating the SAP basis with other IT departments, the optimisation is always done in the overall context of the company or the IT organisation. Eliminating the separation of SAP and non-SAP topics in areas where it is considered useful will lead to expert groups and synergy effects through centralisation.

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 at this layer. These application servers provide all the services required by the SAP applications. In theory, a single server could fill this role. In practice, these services are in most cases distributed among several servers, each serving different applications.
