System replication is better

In practice, it is quite possible that the target specifications defined in the security concept do not match the current actual status. Therefore, especially with regard to SAP security, it must always be checked whether the necessary SAP basic settings also correspond to the minimum level. Although a manual check is possible, it is very time-consuming because the necessary regularizations have to be read, interpreted and technically implemented. The Security Architect - part of the Xiting Authorizations Management Suite (XAMS) software solution developed by Xiting - offers you the possibility to precisely examine the current status of the SAP Basis settings with the help of the integrated check mode, whereby it is also possible to check several systems via RFC, starting from a central system. The scope of the check of system settings and system security includes not only the SAP Basis settings presented here, but also other SAP Basis settings. The scope of the check mode can be extended by self-defined check IDs.
Following the recommendation of dividing the SAP basis into an application-orientated and infrastructure-related SAP basis [A4], Figure 3 shows a possible presentation form. The SAP-Basis interface function is structured into a SAP basis, which is close to the application and is responsible for coordination and communication with vertical and higher IT specialist and business areas, and a SAP basis close to the infrastructure. The infrastructure-related SAP basis in turn serves as the link between the application-orientated SAP basis and the infrastructure levels. Subject Matter Experts will perform the link task again. In the application-orientated SAP basis, in turn, technology architects are more likely to be placed. The innovation activity or innovation team aspect of the SAP basis is placed at the level of the SAP basis, which is close to the application, because the existing capabilities allow it to assume a leading, also coordinating role and acquire expertise both by adding the SAP basis near the infrastructure and the downstream IT departments.

Before SAP HANA was released, there was no SAP database - you had to install SAP ERP (or the application you were using) on a third-party database, such as Oracle or SQL Server. SAP developed the HANA database to fully leverage the power of SAP's next-generation S/4 software.
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:
Tools such as "Shortcut for SAP Systems" are extremely useful in basic administration.
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.
In many companies, the boundaries between administration and development are blurred.
