This opens up new possibilities for SAP administration. Basic services, for example, can also be rented from SAP or obtained from an external service provider as part of managed services.
In the SAP Basis area, it is necessary to make temporary changes to the security settings of clients and systems in the course of system updates. You can use the system changeability variable to specify whether changeability of cross-client data, such as programs or menus, and cross-client customizing is allowed.
SAP BASIS AND DATABASE SERVICE
Database layer: All of a company's data is stored in the database, which is located on a database server. Application programs pull the data they need from the database. This data can consist of data tables, applications or system control tables. In addition, the database also takes new information from users and backs it up.
An important area of SAP Security is the analysis of the customer's own SAP programs, which are classically written in the proprietary SAP language ABAP. Here, too, as in all programming languages, security vulnerabilities can be programmed - whether consciously or unconsciously. However, the patterns of security vulnerabilities in ABAP code differ from those in Java stacks or Windows programs. The goal of these conventional programs is usually to either crash the program (buffer overflow) or to artificially execute the program's own code (code injection). Both is not possible in ABAP, since a crash of a process causes nothing else than the creation of an entry in the log database (Dump ST22) and a subsequent termination of the report with return to the menu starting point. So a direct manipulation as in other high level languages or servers is not possible. However, there are other manipulation possibilities.
Use "Shortcut for SAP Systems" to accomplish many tasks in the SAP basis more easily and quickly.
Here, SAP offers the possibility of logging changes to critical tables through table logging.
SAP Basis is the foundation of any SAP system. You can find a lot of useful information about it on this page: www.sap-corner.de.
In addition, when copies are transported to the test system, no import is created in the production system.
