QUICK CHECK OF YOUR SAP SECURITY SETTINGS WITH THE XITING AUTHORIZATIONS MANAGEMENT SUITE (XAMS)
Execution of release changes and upgrade projects
If your system is already above SAP NetWeaver Release 7.0, then you must either import SAP Note 1731549 or a corresponding Support Package. Afterwards, when creating new users, it is no longer possible to assign user names that are only composed of variants of spaces or other invisible special characters. Important: Changes to already existing users with these names or their deletion option are not affected by this! The SAP Note also adds the customizing switch BNAME_RESTRICT, whereupon you can control yourself whether alternative spaces are allowed to appear in certain places in the user name. For this, the following values must be set in the customizing table PRGN_CUST: NO = The alternative spaces are still allowed in the user name. ALL = The character set is reduced to a defined range, excluding certain special characters because they have specific meanings in certain operating systems or databases. This predefined character set is: ABCDEFGHIJKLNMOPQRSTUVWXYZ_0123456789,;-§&()={[]}+#. FME = The letters F, M and E stand for Front, Middle and End. With an 'X' in this three-digit switch value you can now explicitly specify at which position in the user name no wide spaces and control characters may occur. All combinations are possible, e.g.: XME = None of these special characters may occur at the BEGINNING of the user name. XMX = In the user name none of these special characters may occur at the BEGINNING and at the END. FME = One of these special characters may occur at any position in the user name (this corresponds to the default setting, i.e. as if no entry was maintained in PRGN_CUST for the switch). SAP recommends the use of the value ALL.
Understanding the structure and functioning of the system is particularly important for IT administration. It is not for nothing that "SAP Basis Administrator" is a career field in its own right. Instead of data and application development, the focus here is on providing the software environment on which the company's tools are created. SAP Basis is therefore comparable to the server and platform infrastructure and its administration in companies - as distinct from application and web development.
Version upgrades
The SAP Basis & Technology department deals intensively with SAP technologies and their application. The possibilities and limits are examined and corresponding specifications and tools are developed in order to use the technologies profitably. The results and findings are made available to the other alogis areas and implemented in real-life customer projects.
As a hint: The menu tab "Jump" allows you to set all namespaces or software components simultaneously to "modifiable" or "non-modifiable". However, before you can rearrange the namespace and software components, you must also adjust the global setting accordingly. With Save or CTRL+S you can now save your new settings and you have already set the system modifiability.
Tools such as "Shortcut for SAP Systems" complement missing functions in the SAP basis area.
The presentation layer is used to visualize the applications and data for the user.
It defines requirements for the implementation and operation, which it aligns with the operator or with the necessary expression of the Subject Matter Expert.
