Redesign of SAP® Authorizations
Authorization roles (transaction PFCG)
The next step is to maintain the permission values. Here, too, you can take advantage of the values of the permission trace. When you switch from the Role menu to the Permissions tab, you will generate startup permissions for all applications on the Role menu and display default permissions from the permissions suggestions. You can now add these suggested values to the trace data by clicking the button trace in the Button bar. First, select the authorization object that you want to maintain. There can be multiple permissions for each authorization object. Then load the trace data by clicking the Evaluate Trace button. A new window will open again, where you can set the evaluation criteria for the trace and limit the filter for applications either to applications in the menu or to all applications. Once the trace has been evaluated, you will be presented with all checked permission values for the selected authorization object. With the Apply button, you can now take the values line by line, column by column, or field by field.
You can also evaluate the application log through the SLG1 (ATAX object) transaction; the output of the report CA_TAXLOG seems more useful here. Finally, we have some important information for you: There are individual programmes that can be used read-only, but also offer options for updates to the database. In these cases, additional logic was implemented (e.g. in SAP Note 925217 to the RFUMSV00 programme for the sales tax pre-reporting). Action log data can be accessed via the transaction SLG2 (Object: ATAX) (see also SAP Note 530733). If you want to customise for the annual permissions directly in the production system (so-called "current setting"), the SAP Note 782707 describes how to do this. Basic information about Current Settings is provided in SAP Notes 135028 and 356483. SAP Note 788313 describes in detail the functional components of the time-space test and the additional logging and also serves as a "cookbook" to use in customer-specific developments. How you can prevent access to the SAP menu and only show the user menu to the user, we described in Tip 47, "Customising User and Permissions Management".
Change management
Customising roles are temporary because of their project nature. Therefore, when assigning users, maintain the end date. You cannot also map transactions manually if you created a role directly from a project or project view. Conversely, you cannot use an existing transaction role in the menu as a customising role. The transactions associated with a customising role are not displayed in the Session Manager or the SAP Easy Access menu, but can only be viewed through the view in the customising.
Critical permissions are permissions that allow you to view or modify security-related configurations in the SAP system, or perform activities that are critical from a legal or business perspective. This also includes access to sensitive data, which are e.g. personal. Critical permissions are really critical in themselves and pose a risk only if they get into the wrong hands. In any case, when using critical permissions, you should observe the principle of restricting rights. There are no general definitions of risk; Therefore, each company should define the compliance requirements for itself. Identifying critical SAP permissions is an important task and should be performed in every company. Particular attention should be paid not only to the award of transactions but also to the value characteristics of each of the eligible objects. It is important to mention that preventive regular inspections do not have to be burdensome. However, they will lead to greater transparency and security.
The possibility of assigning authorizations during the go-live can be additionally secured by using "Shortcut for SAP systems".
To disable the ZBV completely, use the RSDELCUA report or the Delete button in the transaction SCUA.
In running operations, scheduled batch jobs may be cancelled because a step user is deleted or locked.
