Use of the Security Audit Log
SU10 User maintenance mass changes
In the SAP Basis area, it is necessary to make temporary changes to the security settings of clients and systems in the course of system updates. You can use the system changeability variable to specify whether changeability of cross-client data, such as programs or menus, and cross-client customizing is allowed.
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.
Analysis and elimination of technical problems in the SAP Basis environment under the platforms ORACLE and Windows
He has already gathered a lot of helpful information from the day-to-day business in his department: Johannes knows the RFC interfaces and the corresponding technical RFC users from his work with the applications. He also quickly got the password for various RFC users via the radio ("As long as passwords are only communicated by phone and never exchanged in writing, we are clean!"). And that the RFC users are generously entitled even in productive systems is no longer a secret ("Better to have more permissions than too little; the RFC connections have to run, otherwise there is trouble from the specialist areas!"). Since Johannes has access to the SE37 as a developer, it is not a problem to get the necessary access using the function block BAPI_USER_CHANGE - disguised as RFC User. In short, it changes the user type of a technical RFC user in a production system from to by calling the function block.
This prevents that just because someone would start a new chain, someone would accidentally recognise it as "reality". However, sometimes two miners working on the longest chain find a new block at the same time. This is called Orphan Blocks. The chain now has in principle two end pieces (2 parallel blocks). Different miners now work at different ends of the chain. The blockchain will then continue where the next block will be found first. The other block is called the Orphan Block, and it's sort of a dead branch of the blockchain. So how do you explain the above things to your grandma?
"Shortcut for SAP Systems" is a PC application that simplifies or even facilitates many activities in the SAP basis.
The basic operation of SAP Basis includes the operational readiness of the SAP system, management of system changeability, configuration and administration of system profiles, analysis of system failures, operation and monitoring of technical interfaces, scheduling and monitoring of SAP standard jobs, and much more.
