SAP Basis: the heart of the SAP system
Controlling users and access rights
The so-called SAP message server also belongs to the application layer. Only one instance of this server exists in the system. It mediates between the services and applications. In concrete terms, this means that the message server takes care of load balancing and determines, for example, on which application server a user logs on. Communication between application servers is also the domain of this message server.
This is where all the system's data resides. These are composed of the actual database and the DBMS, the "database management system". In earlier versions, the database here came from different manufacturers. For example, Microsoft SQL or Oracle. Since SAP HANA, a lot has changed for IT in this data layer. This is because the database comes from SAP itself and is automatically monitored by the system. There is more to this database layer than just the working data. Important elements such as the configuration tables and system data for control and application content are also stored here. This is the repository data used by applications.
Rights-based workflows in accounting

Projects: Your SAP Basis administrator plays a key role in planning and executing system upgrades and migrations. He is also responsible for transport management and tests software updates to ensure they are compatible with the landscape. In addition, he must ensure that they are installed in the correct order.

This means that only the tables or table permission groups for which the corresponding values in the aforementioned permission objects are assigned can be accessed.
