Limitations of authorization tools
Edit Old Stand
In the SAP standard, there is no universally applicable way to automate the mass maintenance of role derivations. We therefore present three possible approaches: 1) Approach to custom development 2) Automated mass maintenance using the Business Role Management component 3) Use of a pilot note that allows a report for mass update of organisational values in rolls (currently available to selected customers) (BRM) from SAP Access Control.
Authorization tools are only as good as the person using them. Until now, no tool has made it possible to create ready-made authorization concepts with just a single click.
Set up permissions to access specific CO-PA measures
If you want to allow users to access only individual table rows, you can use the S_TABU_LIN authorization object, which allows access to specific rows of a table for defined organisational criteria. A prerequisite for this type of permission is that the tables have columns with such organisational values, such as the work, country, accounting area, etc. You must now configure these organisational values in the system as organisational criteria that represent business areas; serve as a bridge between the organisational columns in the tables and the permission field in the authorization object. Since the organisational criteria are found in several tables, this eligibility check need not be bound to specific tables and can be defined across tables.
You can adjust these evaluation methods in the table T77AW or in the transaction OOAW. To do this, select the respective evaluation path by selecting it, and click on the evaluation path (individual maintenance) in the menu on the left. The table that appears defines the relationships between the objects. For SAP CRM only the objects Organisational Unit (O), Headquarters (S), Central Person (CP) and User (US) play a role. For simplicity, you can now copy the lines that use the Person (P) object. Enter a new number here and replace the object P with the object CP.
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.
At www.sap-corner.de you will also find a lot of useful information on the subject of SAP authorizations.
Furthermore, access to financial data of subdivisions of a group, such as individual business units or companies, must be restricted to those employees who are allowed to access it because their current activities require it.
To review your need for action in this area, I advise you to ask yourself the following questions: Do you know which users get which SAP authorizations and why? Can you explain the concept to your data protection officer? Is it easy for you to introduce a new process because you know how the authorizations work? If you have to answer "no" here (several times), I recommend you to dedicate yourself to the topic.
