Maintain table permission groups
Evaluate Permission Traces across Application Servers
Do you want to keep track of what changes have been made to the Central User Management configuration or the distribution parameters for the User Master's Care? You can manage the change documents centrally. The Central User Administration (ZBV) is used to create users, assign roles and distribute them to the respective subsidiary systems. For this, the ZBV has to be configured initially. These include defining the ZBV landscape, i.e. defining the central system and subsidiary systems, adjusting the distribution parameters and transferring users from the subsidiary systems to the central system. You can also configure the ZBV afterwards. For example, you can add subsidiary systems or release them from the ZBV. In the transaction, you can modify SCUM to change the field allocation properties so that fields that were originally globally distributed across the ZBVs are also locally maintainable. All this information about the changes to the ZBV configuration has not been centrally logged.
The customising parameters in the table PRGN_CUST control the password generator in the transactions SU01 and SU10. The values of the profile parameters override the customising parameter entries to prevent invalid passwords from being generated. If the value of a customising parameter is less than the value of the corresponding profile parameter, the default value of the customising parameter is drawn instead. The same is true if no value is maintained. You can exclude certain words or special characters as passwords by entering them in the USR40 table. In this table you can enter both specific passwords (e.g. your company's name) and patterns for passwords (e.g. 1234*). '*' stands for any number of additional characters (wild card) and '?' for any character. However, when maintaining the USR40 table, note that the number and type of entries affect performance.
Note the maintenance status of permissions in roles and their impact
The SAP NetWeaver Application Server ABAP 7.31 changed the way the transaction SU25 works, especially from step 2a to the automatic suggestion value matching with SAP values. Now, this compares which records have been updated using time stamps. This makes it possible to run Step 2a separately for software components installed afterwards. Another advantage is that the objects to be edited can be better identified due to the time stamp. Before SAP NetWeaver 7.31, the applications to be matched for step 2a have been registered with their base release versions, which you can see in the USOB_MOD or TCODE_MOD tables.
If you want your own developments to meet your security requirements, just like the standard, you must assign table permission groups to the custom tables. Custom tables, or SAP standard tables that you want to protect in particular, belong to separate, if applicable, customer-specific table permission groups. If extensive permissions are to be granted for system administration or certain applications, this is done with the S_TABU_DIS authorization object for the table permission group. Since many standard tables do not have a table permission group assigned to them and therefore automatically end up in the table permission group &NC&, you should restrict access to this table permission group. For example, certain tables such as T000 (clients) are in a large table permission group (SS: RS: SAP control); therefore, it is better to restrict access via a separate table permission group. You should also always assign custom tables to a table permission group, otherwise they will also be assigned the table permission group &NC&. Therefore, we will explain below how you can create table permission groups and map tables.
Authorizations can also be assigned via "Shortcut for SAP systems".
So you can call exactly the authorization trace and set the filter on a user.
For the BAdI BADI_ IDENTITY_UPDATE, you must implement the SAVE method to the IF_BADI_IDENTITY_UPDATE interface.
