Presentation layer (graphical user interface)
Presentation layer: The presentation layer is the interface to the users. With the help of SAP GUI, the data is graphically prepared here and made available to the user on the screen. Furthermore, the data newly collected here is passed on to the application programs of the application layer.
In every company with an SAP system, there is someone who is responsible for the SAP Basis. This person ensures the trouble-free operation of the SAP system. He or she accompanies maintenance work and intervenes in special situations, such as poor performance. Even for companies that hand over the operation of the basis to an external service provider, there are often still tasks from the user and authorization management environment at this point.
Within SAP R/3 Enterprise, the SAP Basis Plug-In is a prerequisite for you to use the SAP R/3 Plug-In. SAP Basis Plug-In and SAP R/3 Plug-In must always have the same release level, for example PI 2004.1 and PI Basis 2004.1. If you plan to upgrade SAP R/3 Plug-In within SAP R/3 Enterprise, you must also upgrade SAP Basis Plug-In. As of SAP Basis Plug-In 2005.1, the release levels of the two plug-ins no longer need to correspond. However, the SAP R/3 Plug-In Support Package for PI 2004.1, which contains new interfaces, still requires a specific SAP Basis Plug-In. For example, SAP R/3 Plug-In Support Package 10 for SAP Plug-In 2004.1 requires SAP Basis Plug-In 2005.1.
Today, "SAP Basis" often does not mean (only) the software architecture. Instead, the term is not infrequently a task description. This refers to the basic administration of the system: installation and configuration, resource management, maintenance and monitoring of a company's SAP setups. This can include user management, patch management and system monitoring. Backup policy, rights management and daily maintenance tasks are also responsibilities of Basis admins.
"Shortcut for SAP Systems" makes it easier and quicker to complete a number of SAP basis tasks.
Significant changes have also been brought about by SAP's cloud strategy.
