Customising User and Permissions Management
Over the course of time, many companies experience profound changes in the framework conditions that significantly influence SAP® authorization management. Not uncommon are subsequent requirements from the area of compliance (SOX or similar) or the increased need for protection.
Service users are used for multi-person anonymous access, such as Web services. This type of user is also dialogical, i.e. it can log on to the SAP system via SAP GUI. With a service user, multiple logins are always possible, and password modification rules do not work. This behaviour has changed with the introduction of security policy. Because previously all password rules for the service user were invalid, and now the rules for the contents of the passwords also apply to the service user (see Tip 5, "Defining User Security Policy" for details on security policy). The password of a service user always has the status Productive and can only be changed by the user administrator.
To do this, first define what information should be checked. In the SU20 transaction, verify that the required fields may already exist as permission fields. If you want to check custom fields, you must create your own permission fields in the transaction SU20. Please pay particular attention to the (F4) help provided. When defining customised permission fields, you assign a name in the Field Name field that is in your Customer Name Room and assign the corresponding data element and, if desired, a table name for a value help. The next step is to create your own authorization object and assign your permission fields and, if necessary, default permission fields. If you use the ACTVT field to validate the activity, you must use the Activities allowed button to select the activities that you want to validate from the source code of your programme. For recommendations on the naming conventions for authorization objects, see SAP Note 395083.
If the system trace has recorded permission data for this authorization object, it will appear in the right pane of the window. In the left pane, you can see the existing suggestion values. If you notice that you do not have any suggestion values that you think are necessary and have been recorded by the trace, you can set the suggestion values to Yes by selecting the appropriate row, column or field in the right pane and clicking the Apply button. You are free to make any manual adjustments to the field values. Afterwards, confirm maintenance and your changes are saved for this authorization object. Do the same for all other authorization objects.
During go-live, the assignment of necessary authorizations is particularly time-critical. The "Shortcut for SAP systems" application provides functions for this purpose, so that the go-live does not get bogged down because of missing authorizations.
Before starting to read the data from the database, a DUMMY check can be used to quickly determine whether the user is authorized to access part of the data.
