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.
The lifecycle of an SAP system begins with the installation of the database platform. This is installed by an SAP Basis administrator and can consist of one of the following databases: HANA, Sybase, DB2, Oracle, MSSQL and MaxDB.
Implentation of the Security Audit Log (SAL)
The so-called SAP message server also belongs to the application layer. Only one instance of this server exists in the system. It mediates between the services and applications. In concrete terms, this means that the message server takes care of load balancing and determines, for example, on which application server a user logs on. Communication between application servers is also the domain of this message server.
Understanding the structure and functioning of the system is especially important for IT administration. It is not for nothing that "SAP Basis Administrator" is a separate professional field. On the page www.sap-corner.de you will find useful information on this topic.
For the authorisation requirement of a user, the transactions with user assignment already awarded should be determined accordingly, in order to be able to exclude them when selecting a suitable role. How does this work? There are various ways to identify specific user-assigned transactions, with varying degrees of result. The following article presents two variants. The first section first describes how to use SUIM to address the problem and what problems are encountered. It then explains how the task can be solved by using the transaction SE16N. As in the previous blog post Identifying all transactions of multiple roles, the roles Test_Schmidt1 and Test_Schmidt2 are used for this. Two of the transactions MM01, MM02, MM03 and MM04 were assigned to these roles in different ways. In the Test_Schmidt1 role, the transactions MM01 and MM02 were entered in the Role menu. In the Test_Schmidt2 role, the transaction MM03 was maintained in the menu of the role, but the transaction MM04 was maintained only in the S_TCODE permission object of the role. Both roles have been assigned to the user SCHMIDT_TEST. Identification of certain transactions with user assignment using SUIM This option is useful if only one transaction is to be checked for its existing assignment to a particular user. The audit is carried out here by means of the transaction SUIM. For this purpose, the variant "Roles according to complex selection criteria" has to be executed in the SUIM. After activating the option "With valid assignment of", the corresponding user and the transaction to be checked will be entered here. It is also recommended to hide the display of the collection roles in the search results.
For administrators, a useful product - "Shortcut for SAP Systems" - is available in the SAP basis area.
SAP Basis Consulting is a technical consulting service that covers many tasks and sub-areas related to SAP Basis.
The freeware Scribble Papers is a "note box" in which all kinds of data can be stored. It takes in typed texts as well as graphics and entire documents. The data is then organised in folders and pages.
Tasks such as the update of components, the insertion of security updates or monitoring should be further automated.
