User & Authorization Management with SIVIS as a Service
Do this once in your system. For example, you can jump from the MM50 transaction to the MM01 transaction without explicitly assigning transaction startup permission to the MM01 transaction through the S_TCODE authorization object. You can see this call in your System Trace for Permissions in the Additional Information column for testing. There you can see that the CALL TRANSACTION call has disabled the permission check. The user is allowed to jump into the transaction MM01, although in the role assigned to him Z_MATERIALSTAMMDATEN only permissions for the transactions MM03 and MM50 are recorded.
Add SAP Note 1695113 to your system. With this note, the RSUSR200 and RSUSR002 reports are extended by the selection of different user locks or validity. In the selection, you can now distinguish whether you want to include or exclude users with administrator or password locks in the selection. In addition, you can select in the report RSUSR200 whether the users should be valid on the day of selection or not. To do this, select whether you want to select the user locks as set (01 set) or not set (02 not set) in the selection screen of the RSUSR200 report in the Locking after Lock section of the User Locks (Administrator) field. This includes local and global administrator locks. In the same section, you can also select the password locks (false logins) as set (01 set) or not set (02 not set). This will filter for users that are locked because of incorrect password messages and for which a password login is no longer possible. You can select these selection criteria together or separately. Alternatively, you can also use the Use only users without locks option and additionally, in the Selecting after the user is valid between user today and user today, select not valid.
Use the authorisation route to identify proposed values for customer developments
The passwords of the users are stored in the SAP system as hash values. The quality of the hash values and thus their safety, however, depends on the hash algorithms used. The hash algorithms previously used in SAP systems are no longer considered safe; They can be cracked in a short time using simple technical means. You should therefore protect the passwords in your system in various ways. First, you should severely limit access to the tables where the hash values of the passwords are stored. This applies to the USR02 and USH02 tables and in more recent releases the USRPWDHISTORY table. The best way to assign a separate table permission group to these tables is to do so, as described in Tip 55, "Maintain table permission groups". In addition, you should also control the accesses using the S_TABU_NAM authorization object.
The general SAP authorizations are used most often and for many things they are sufficient. For example, if only the HR department has access to the SAP HCM system. However, if other users come onto the system and you only want to allow them access to a limited number of personnel, then in the case of the general authorizations you have to deal with the organization key of infotype 1 (VSDK1), which must be hard-coded into the authorization roles. If ESS/MSS or Manager Desktop etc. now come into play, however, this means a large number of authorization roles, namely a separate one for each manager. This makes maintenance and servicing very time-consuming and your authorization concept becomes opaque, which in turn brings the much-quoted auditor onto the scene.
Assigning a role for a limited period of time is done in seconds with "Shortcut for SAP systems" and allows you to quickly continue your go-live.
These are displayed in the role menu of the PFCG role.
