Set up operating modes
Administrative tasks
In the beginning, in our company the installation and management of the systems were dealt with by the functional consultants/consultants of the respective systems. The CRM consultant was responsible for the SAP CRM system, the SRM consultant for the SAP SRM, etc.
SAP Basis is responsible for the smooth operation of the SAP Basis system. The SAP Basis system is like an operating system for R/3 as well as S/4. Every operating system, such as Windows, provides an environment in which programs developed for that environment can run, such as MS Office. Likewise, the SAP Basis system provides an environment in which SAP programs can run. In any R/3 or S/4 system, there is a database server, such as HANA, where the database resides. It provides the necessary data to all other applications. The data here is not only data tables, but also applications, system control tables and user data.
Decommissioning/uninstallation of SAP systems and their databases
In order to ensure the stability of the systems and to reduce the risk through proprietary developments, release and patch management must be implemented. Standardised procedures can help to introduce proprietary developments, such as test strategies or service level agreements (SLAs). It is also important to align the productivity setting of customer applications with the maintenance windows and RTO (Recovery-Time-Objective).
A trick often used by administrators is to allow for time buffers before starting the next job. The buffer times are necessary because it is not possible to predict exactly how long a job will take to complete, since the duration depends on many incalculable parameters. Since it makes little sense to run backups and SAP jobs at the same time, these tasks are usually done one after the other rather than in parallel. 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. Tools that work with status dependencies and then automatically start the next job when its predecessor job has been processed without errors can help here.
"Shortcut for SAP Systems" simplifies tasks in the area of the SAP basis and complements missing functions of the standard.
