AUTHORIZATIONS IN SAP SYSTEMS
User Interface Client Permissions
On the topic of SAP authorizations and SAP S/4HANA, I can recommend the SAP online course by Tobias Harmes as blended learning from Espresso Tutorials for SAP administrators, ABAP developers and people who are currently or will be dealing with SAP authorizations. The online course covers the following topics: - Introduction to the course - Why are SAP authorizations actually important? - How do SAP authorizations work technically? - Developing and maintaining roles - SAP Fiori authorizations/tile authorizations in S/4HANA - Developing authorization checks.
If you use configuration validation, we still recommend that you use the AGS Security Services, such as the EarlyWatch Alerts and SAP Security Optimisation Services, which we describe in Tip 93, "AGS Security Services." SAP keeps the specifications and recommendations in the AGS Security Services up to date and adapts them to new attack methods and security specifications. If you have identified new security issues within a security service, you can set your target systems accordingly and monitor these aspects in the future.
Default permissions already included
The assignment of combinations of critical authorizations (e.g., posting an invoice and starting a payment run), commonly known as "segregation of duties conflicts," must also be reviewed and, if necessary, clarified with those responsible in the business departments as to why these exist in the system. If compensating controls have been implemented for this purpose, it is helpful if the IT department also knows about this so that it can name these controls to the IT auditor. The IT auditor can then pass this information on to his or her auditor colleagues.
A mass rolling out of rolls is a very useful thing. It is also possible to use Excel-based data - as in the case of the outlined application case with eCATT - because it is a one-time action for the roles considered and SAP standard programmes are used in the background. However, ongoing maintenance of the permissions system, with continuous changes to roles and their detail permissions, requires the mapping of much more complex operations. An exclusive control over Office programmes should be well considered. This does not mean, of course, that there are not very good partner products for the care of roles. Simply verify that SAP standard procedures are used and that authorisation is managed in accordance with SAP best practices.
Secure your go-live additionally with "Shortcut for SAP systems". You can assign necessary SAP authorizations quickly and easily directly in the system.
But restructuring must also be carried out at the organizational level.
If there is a change or difference in applications (changed check marks, suggestions, field values, or new or deleted authorization objects), the USOB_MOD or TCODE_MOD table of the MOD_TYPE is set to M.
