Equal permissions
SAP FICO Authorizations
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.
In the foreground, important SAP reports on the subject of role and authorization administration were presented. Since these and the entire SAP system are known to be based on ABAP coding, the analysis of the source code is just as important, especially when using in-house developments. These in-house developments often present serious security vulnerabilities because they have insufficient authorization checks in the coding. To search for explicit strings and to categorize the in-house developments accordingly, the report RS_ABAP_SOURCE_SCAN can be used. This allows existing programs in the backend to be explicitly checked for specific check patterns by the authorization administrator and any errors to be corrected by the relevant developers. Authorization-relevant check patterns for such a scan are, for example, "AUTHORITY-CHECK" or SQL statements such as SELECT, UPDATE or DELETE. The former checks whether authorization checks are present in the source code at all. The check for Open SQL patterns analyzes the code structure for direct SELECT, MODIFY or INSERT statements that must be avoided or protected on the authorization side. The best practice measure in this case is to use SAP BAPIs. The preventive best practice would be to involve developers and authorization administrators equally during the conceptual design of the custom development.
Criticality
This report not only gives you an overview of the table logging settings in the tables, but also allows you to select multiple tables for logging. The Log flag button allows you to set the table logging check for all previously selected tables. The current status of the table loggers for the tables can be found in the Protocol column. The icon means that the table logger for the selected table is off.
You will also notice that many tables have the table permission group &NC& assigned to them, and therefore differentiation over table permission groups over the S_TABU_DIS authorization object would not work at all. Furthermore, you cannot assign permissions to only individual tables in a table permission group using S_TABU_DIS. In such cases, the investigation shall continue: If the permission check on the S_TABU_DIS authorization object fails, the S_TABU_NAM authorization object is checked next. Allows you to explicitly grant access to tables by using the table name.
However, if your Identity Management system is currently not available or the approval path is interrupted, you can still assign urgently needed authorizations with "Shortcut for SAP systems".
The tool creates a clear overview of which data certain users are allowed to access in the SAP system.
By default, the profile parameter is active in SAP systems (profile parameter transport/systemtype = SAP) and inactive in customer systems (profile parameter transport/systemtype = CUSTOMER).
