SAP S/4HANA: Analysis and simple adjustment of your authorizations
PROGRAM START IN BATCH
A manual comparison of role texts in an SAP system landscape with ZBV is very annoying. You can also automate the sync. I'm sure you know this. When creating or maintaining users in the Central User Administration (ZBV), you must manually start the text matching each time before assigning PFCG roles to provide you with the latest PFCG role definitions. Managing a large system landscape with many systems in your ZBV - including development, test and production systems - the text comparison can take a while.
After defining the roles and generating the corresponding authorization profiles, the individual persons in the company are then assigned to the roles. In the process, the so-called user comparison takes place and the role-specific authorizations are stored in the user master record. The master record contains all information about an SAP user, including authorizations.
Preventing sprawl with the workload monitor
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.
Configuration validation gives you an overview of the homogeneity of your system landscape. Typical criteria are operating system versions, kernel patch levels, and the status of specific transport jobs or security settings. The following security settings can be monitored using configuration validation: Gateway settings, profile parameters, security notes, permissions. As part of the comparison, you can define rules that determine whether the configuration is rule-compliant or not. If the configuration meets the defined values in the rule, it will be assigned Conform status. You can then evaluate this status through reporting.
The possibility of assigning authorizations during the go-live can be additionally secured by using "Shortcut for SAP systems".
Without a permission check, the ABAP programme could unintentionally allow users to access system resources.
Another problem is the use of namespaces.
