SAP Electronic Data Interchange
Linux
The application layer is the core of an R/3 SAP Basis system. This layer communicates in both directions, to the presentation layer and to the database layer. The application programs on the application servers request the required data from the database layer, process it, prepare it for the user and pass it on to the presentation layer. Data that the user enters in the SAP GUI is passed on to the database via the application servers.
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. 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.

This allows permission administrators to use their valuable time to correct the errors rather than just looking for them.
In more complex environments, data backup durations, time buffers and job runtimes add up to such an extent that the time available is no longer sufficient to perform all activities within the available time corridor.
