Configuration as well as maintenance, upgrades and backup & recovery
The Basis system comprises a total of three layers (Figure 1):
First you have to create an area menu in the area menu maintenance with the transaction code SE43 or SE43N. Then add the created menu to the SAP standard menu S000.
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.
BENEFITS & CONSEQUENCES
The SAP Basis is responsible for the smooth operation of the programmes in the SAP system. It acts as an operating system for R/3 and subsequent releases including S/4HANA. Each operating system provides an environment in which programmes can run, such as MS Office on Microsoft Windows. Likewise, the SAP base system with the NetWeaver and HANA platform offers an environment in which the SAP programmes can run. In this context, the NetWeaver platform itself relies on server operating systems such as Windows and Linux.
A first important step was the introduction of playbooks to professionalize our work. Back then, SAP installation manuals were real tomes with hundreds of pages that often went around in circles and were anything but easy to understand....
Tools such as "Shortcut for SAP Systems" are extremely useful in basic administration.
