Monitoring of the SAP system landscape through regular system checks according to defined schedules and workflows
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.
Basis comprises a number of middleware programs and tools from SAP. Basis is responsible for the smooth operation of the SAP Basis system and thus for R/3 and SAP ERP, for example. SAP thus provides the underlying basis (hence the name) that enables various SAP applications to be interoperable and portable across operating systems and databases.

The main benefit of the implementation of the above recommendations lies in the creation and documentation of the innovative power of the SAP basis. Through consistent research and testing, the SAP basis is enabled to assume its role as an innovation driver. It also creates an attractive and exciting working environment for employees. By being involved in projects in a timely manner, project success will be promoted and will contribute to company success in the medium and long term. One possible consequence of the constant overuse of the employees is the reorientation of the employees and the associated loss of knowledge. This can also lead to the complete basic activity being carried out by external partners, to which a dependency relationship then arises.
User name without restrictions - critical? Depending on the release of the SAP_BASIS component in your system, invisible special characters may end up in the user name. This is especially critical if only spaces or alternate spaces are used for the user name when creating a new user. In Unicode systems, "alternative" spaces, so-called "wide spaces", can be used in addition to the normal space character (hexadecimal value 20). For example, the key combination "ALT+0160" can be used to insert non-breaking spaces. If a user is now created whose user name consists exclusively of such alternative spaces, this can be confusing. This is because entries for this user ID do appear in change documents, but the impression is created that the entry was created by a non-existent / deleted user. This circumstance can lead to confusion. In addition, certain special characters in the user name can also lead to errors, for example in the Change and Transport System (CTS). This is because the user name is also used in the CTS-ORG to create a file with the same name in the transport directory. Furthermore, there are letters/characters that look identical in different alphabets, but have a different hexadecimal value in the character set. This means that confusion in user names cannot be completely ruled out. Seemingly identical user names then stand for different users.
For administrators, a useful product - "Shortcut for SAP Systems" - is available in the SAP basis area.
