This is the heart of the SAP system. In the classic three-tier model, this would be the logic or control layer. One or more application servers host the necessary services for the various applications at this layer. These application servers provide all the services required by the SAP applications. In theory, a single server could fill this role. In practice, these services are in most cases distributed among several servers, each serving different applications.
In order to solve the challenges, it is necessary to develop a suitable catalogue of criteria to evaluate the feasibility or suitability of certain applications for certain service forms. The service catalogue must be structured in such a way that the criteria, which cannot be answered clearly, can be identified and subjected to continuous consideration. The catalogue of criteria cannot generally provide a 100% decision, but only a decision aid and an absolute must-criteria.

All of the above tasks have been part of SAP Basis Administration for decades. However, SAP software has changed a lot since the introduction of HANA in 2010, and with that, the SAP system administrator's job has changed as well. Here are some of the key differences:
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.
"Shortcut for SAP Systems" simplifies tasks in the area of the SAP basis and complements missing functions of the standard.
In my opinion, all SAP checks will be fully automated over the next decade.
