Defined service level agreements (SLAs)
System modifiability and client control in an SAP system
The prerequisite for employment is a relevant university degree (bachelor's degree, FH diploma) preferably in computer science, business informatics, mathematics or a scientific discipline as well as at least three years of practical experience. Ideally, you also have a completed scientific university education (master's degree, university diploma).
The SAP basis is often perceived as a brake within projects or when introducing new technologies. This is partly due to the late consultation of the SAP basis on the issues of technical feasibility as well as the integration of new technologies and applications into the existing system landscape. By implementing the recommendations, the SAP basis is repositioning itself in parts within the IT organisation. The SAP basis has a clearly defined self-understanding (inward-looking perception) as well as a clear positioning and a defined task area within the IT organisation (outward-facing perception), as shown in Figure 5. By integrating the SAP basis into the development of the IT strategy, the digitisation strategy and a clear communication with the CIO, the SAP basis has the opportunity to deal with technologies and topics at an early stage. As a result, the SAP basis is prepared for requests from business units or other IT departments and has the opportunity to approach them proactively. The SAP basis is supported by an IT service and IT product catalogue, which describes the scope of the SAP basis. For internal communication and communication with external service providers, as well as other suppliers, outsourcing partners or outsourcing partners and cloud service providers, there are up-to-date and meaningful documentation and process descriptions. For the control, measurement and monitoring of external partners, Service Level Agreements and meaningful key figures are also available.

The coverage of old core tasks (such as security or compliance) and new core tasks (such as cloud or mobility) must be increased in the sense of a holistic consideration. This means that certain tasks must be considered not only in the context of the SAP basis, but also in the overall context.

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.
