Dissatisfaction and unclear needs in the process
Schedule PFUD transaction on a regular basis
SAP*: The SAP* user is part of the SAP kernel, and since it is hard-coded in the SAP system, it does not require a user master set. If there is no user master set for SAP*, anyone can log on to the SAP system after rebooting with this user, as the default password will then apply. The user thus has access to all functions, since Authority Checks in this case do not take effect. You can prevent this behaviour by setting the login/no_automatic_user_sapstar profile parameter to 1. If you want to copy clients, you have to set this parameter to 0 again before you do so, because the user SAP* is required for this. Safeguard measures: Despite the parameter setting, the SAP user should have a user master set in all clients. However, you should remove all profiles and lock the user. In addition, change the password, assign the user to the SUPER user group, and log it with the Security Audit Log.
You cannot increase the retention time afterwards; Therefore, you should adjust the configuration in good time before starting a project. In addition, you should change the settings of the stat/rfcrec and stat/rfc/distinct profile parameters. For example, you should increase the value of stat/rfcrec to 30, and stat/rfc/distinct should be set to 1. This improves the completeness of the recorded RFC usage data. For details on the technical improvements, see SAP Note 1964997.
User and authorization management
You can use authorization objects to restrict access to tables or their content through transactions, such as SE16 or SM30. The S_TABU_DIS authorization object allows you to grant access to tables associated with specific table permission groups. You can view, maintain, and assign table permission groups in transaction SE54 (see Tip 55, "Maintain table permission groups"). For example, if an administrator should have access to user management tables, check the permission status using the SE54 transaction. You will notice that all the user management tables are assigned to the SC table permission group.
In the transaction SU01, enter a non-existent user ID and click the Create button (F8). The BAdI BADI_IDENTITY_SU01_CREATE is called with the new user ID. Implementation in the BAdI is running. For example, here you can read additional attributes to the new user from an external data source. The data collected within the BAdIs is written into the fields of the transaction SU01. This will show you the new user master set with the pre-filled fields. You can edit the user master record, such as assign roles, or change the pre-populated fields.
"Shortcut for SAP systems" is a tool that enables the assignment of authorizations even if the IdM system fails.
Using these authorizations, any source code can be executed independently of the actual developer authorizations and thus any action can be performed in the system.
As part of the SAP Access Control solution, the Business Role Management component serves the central role management.
