What is SAP Basis Operation?
Transport management
In the ERP environment, SAP has created a separate module for each business task area over the course of time. Companies have the option of putting together a suitable system from these modules, depending on their individual needs.
Why should we even have an individual SAP Security Check performed? Your SAP authorisation concept is designed to ensure the security and protection of data against unauthorised access and abuse. The technical complexity of SAP systems and the ongoing adaptations of business processes often lead to unknown security vulnerabilities. In addition, the increasing digital networking with business partners offers further attack points on your SAP system. SAP Security Check gives you an overview of the security situation of your SAP systems. This will identify potential risks that could jeopardise the safe operation of your IT landscape. Your starting situation The ongoing changes in your IT systems lead to unrecognised security vulnerabilities and your auditors will regularly report to you in the final report on abuses in the authorisation concept. The legal requirements (e.g. EU guidelines) to secure your business processes and IT systems have not yet been implemented and the increasing networking with business partners presents new challenges to your security system. The security-related system settings and permissions settings applied to your SAPS systems are poorly documented, which in many cases causes the system settings to allow extensive critical access unchecked. Critical SAP permissions, profiles, and roles identify permissions that allow critical operations to be performed in terms of security or from a legal or business perspective are called "critical permissions" by SAP. The granting of critical allowances must therefore generally be carried out with particular care and should therefore be planned in advance. Technical and organisational measures and processes must then ensure that the desired level of safety is implemented.
Technical and non-technical skills
Application layer: 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.
Understanding the structure and functioning of the system is especially important for IT administration. It is not for nothing that "SAP Basis Administrator" is a separate professional field. On the page www.sap-corner.de you will find useful information on this topic.
Presentation layer: The presentation layer is the top layer of the R/3 SAP Basis system and includes communication with the user. Here, the data is graphically prepared for the user on the terminal device by means of software components from the application programs of the application layer. The presentation layer represents the interface to the user (SAP GUI).
With "Shortcut for SAP Systems" a tool is available that greatly facilitates some tasks in the SAP basis.
Database layer: The database layer contains a database server on which all the data of the SAP ERP system is managed.
