Authorization concepts in SAP systems
SIVIS as a Service
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.
When the auth/authorisation_trace parameter is turned on, external services are written to the USOBHASH table and permission checks are logged in the USOB_AUTHVALTRC table. You can now use the contents of this table to apply the checked objects and values from the trace to the suggestion values in the transaction SU24. Because it is a dynamic profile parameter, it is reset when the application server is launched. Now open the transaction SU24 and you will find your own UIK component as an external service. Double-clicking on this service will tell you that no suggestion values have been maintained there. You can apply these suggested values from the USOB_AUTHVALTRC table. Here you should at least maintain the UIU_COMP authorization object so that this information is loaded into the PFCG role as soon as you include the external service in your role menu.
Change management
If you want to set the table logger check for multiple tables, you should note that the principles for changing Dictionary objects apply, i.e. you will generate increased system loads in running systems. Therefore, you should make both the modification and the transport of the changes outside of business hours. The SAP system only provides customising tables for table logging by default; so you don't have to worry about performance. Tables that serve to customise typically contain relatively little data that is rarely changed. However, you should not turn on table logging for tables that are subject to mass changes, as there may be performance and disk space issues. This applies to tables with root or movement data. After all, if table logging is enabled, a log entry in the DBTABLOG table is generated for each change to the contents of a logged table.
The P_ABAP (HR-Reporting) authorization object is not required to execute reports, but is intended to improve performance during execution. In addition, it can be used when reports require permissions for info types that the user should not receive in other cases, which is more common. For example, the right to display information type 0008 (basic salary) is also required for the execution of the travel statement reports. The Invoice Payer Programmes also require P_ABAP permissions to process personal data.
With "Shortcut for SAP systems" you can automate the assignment of roles after a go-live.
Are you using SAP NetWeaver Business Client instead of SAP GUI? The arrangement of the applications on the screen is controlled by PFCG roles.
For this purpose, the SU22 SAP authorization default values must be transported via SU25 into the customer-specific SU24 tables.
