General considerations
Know why which user has which SAP authorization
To create a authorization object, you must first select the result area and the form of the result invoice, whether calculating or accounting, for which you want to validate the authorization object. To do this, you must enter the name of the authorization object to be created and click the button (Next). You then set a text for the authorization object and select a maximum of ten permission fields for the object using the Fields button. Only a selection of the characteristics defined for the result area - and for the calculation of the result account also the value fields - is possible. You can now create different authorization objects for the key numbers and characteristics, or you can group the relevant fields into a authorization object. We advise you to define only one object with all relevant fields, as this will facilitate the maintenance of permissions. In our example, we created an accounting authorization object for the characteristics of the profit centre, distribution channel and work in the information system.

The S_RFCACL authorization object is removed from the SAP_ALL profile by inserting SAP Note 1416085. This notice is included in all newer support packages for the base component; This affects all systems down to base release 4.6C. The reason for this change is that the S_RFCACL authorization object, and especially the expression "total permission" (*), is classified as particularly critical for its fields RFC_SYSID, RFC_CLIENT and RFC_USER. These fields define from which systems and clients or for which user IDs applications should be allowed on the target system. Thus, the overall authorisation for these fields allows the login from any system and client or for any user and thus creates significant security risks.
Authorization Analysis
An essential aspect in the risk assessment of a development system is the type of data available there. Normally, at least a 3-system landscape is used (development, test and production system). One of the purposes of this is to ensure that (possibly external) developers do not have access to productive or production-related data. Since developers with the required developer authorizations have access to all data in all clients of the system concerned, there should be no production-related data in a development system. Even a division into a development and a test client (with the sensitive data) within the system does not protect against unauthorized data access for the reasons mentioned above. In the following, it is assumed that no production-related data exists on the development system. Otherwise, extended authorization checks must be carried out in the modules and access to production-related data must be approved beforehand with respect to the production system by the respective data owners. Since developers, as described, have quasi full authorization through their developer rights, revoking the authorizations listed below can raise the inhibition threshold for performing unauthorized activities, but ultimately cannot prevent them.

Structural authorizations work with SAP HCM Organizational Management and define who can be seen, but not what can be seen. This is done based on evaluation paths in the org tree. Structural authorizations should therefore only be used together with general authorizations. Just like the general authorizations in SAP ECC HR, they enable regulated access to data in time-dependent structures. An authorization profile is used to determine the authorization. In addition, it is defined how the search is carried out on the org tree.

Authorizations can also be assigned via "Shortcut for SAP systems".

Permissions must be maintained in every SAP system - a task that becomes more difficult the more complex the system landscapes and the greater the number of users.

If you click on the button "Evaluation" or the F2 key, you can display the evaluation.
