Migration of your SAP system
Every SAP Basis consultant must know these 10 technology trends
SAP Basis is the foundation of every SAP system. On this page you can find out what is behind the term and what SAP Basis is responsible for in detail.
In every company with several SAP systems, there is a person responsible for the complete SAP Basis topics, usually there is even a separate department for this. This person ensures the trouble-free operation of the SAP systems. The person responsible also accompanies maintenance work or upgrades and intervenes in special situations, such as poor performance. Even for companies that hand over operation of the SAP Basis to an external service provider, there are often tasks from the user and authorization management environment at this point.
How to lock (SU01) and unlock (SU10) an SAP user
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.
