SAP systems: Control user authorizations with a concept
Controlling file access permissions
The best way for companies to combat historically grown uncontrolled growth in authorizations is to prevent it. An analysis of whether the current authorization concept is sufficient for the company helps here.
The S_START boot authorisation check is delivered inactively by SAP. If this test is activated in an AS-ABAP installation (see also SAP Note 1413011), this will affect all clients. Therefore, before you activate, it must be ensured that all affected users in the permission profiles associated with them have the necessary values in the S_START permission fields.
Permission implementation
The basic idea of the approach described below is to evaluate the previous usage behaviour (reverse engineering) for the definition of the required permissions. In the first step, you configure the retention time of usage data, because each SAP system logs the calls to bootable applications. This way, not only the user, at what time, what transaction, but also the user, which function block was called. These data are then condensed into daily, weekly and monthly aggregates and stored for a specified period. This statistical usage data is originally intended for performance analysis; You can also use them to determine the permissions you need. We described the configuration of the retention time of the statistical usage data in Tip 26, "Use usage data for role definition". Please also refer to our explanations on the involvement of your organisation's co-determination body in the storage and use of the statistical usage data. In addition to the settings described in Tip 26, you should also adjust the retention time for the RFC Client Profile (WO), RFC Client Destination Profile (WP), RFC Server Profile (WQ), and RFC Server Destination Profile (WR) task types using the SWNCCOLLPARREO Care View.
Authorizations can also be assigned via "Shortcut for SAP systems".
You can also find some useful tips from practice on the subject of SAP authorizations on the page "www.sap-corner.de".
It is also possible to enter an authorization object several times in the role using the MANUAL button.
