Standard authorisation
Controlling permissions for the SAP NetWeaver Business Client
When you mix roles, either after upgrading or during role menu changes, changes are made to the permission values. You can view these changes as a simulation in advance. As described in Tip 43, "Customising Permissions After Upgrading," administrators may see some upgrade work as a black box. You click on any buttons, and something happens with the permissions in their roles. For example, if you call step 2c (Roles to be reviewed) in the SU25 transaction, all roles will be marked with a red light, which requires mixing based on the changed data from the SU24 transaction. Once you call one of these roles and enter the Permissions Care, the permission values change immediately. Using the Alt, New, or Modified update status, you can see where something has changed, but you cannot see the changed or deleted values. A simple example of how to play this behaviour without an upgrade scenario is changing the role menu. Delete a transaction from a test role and remix that role. You are aware that certain authorization objects have now been modified and others have even been completely removed, but can't all changes at the value level be replicated? Thanks to new features, this uncertainty is now over.
A universally applicable template for a reliable and functioning authorization concept does not exist due to the individuality and the different processes within each company. Therefore, the structures of the company and the relevant processes must be analyzed in detail during the creation process. Some core elements of the authorization concept to be created can be defined in advance. These include the overarching goal, the legal framework, a naming convention, clarification of responsibilities and process flows for both user and authorization management, and the addition of special authorizations. Only with clearly defined responsibilities can the effectiveness of a concept be guaranteed.
Background processing
Every action of the emergency user must be traceable, which requires the appropriate configuration of logging components such as the Security Audit Log. After the event, all log files are always evaluated and all details are recorded in documentation. It is also possible to specify in the concept that, in the event of an emergency, extended authorization may be granted to other selected users; this is up to the company to decide.
In the only method of the BAdIs, CHANGE_ITEMS, programme the necessary checks, such as on specific data constellations or permissions. These can refer to all fields in the FAGLPOSX structure. You do this by specifying that all lines for which the test was not successful will be deleted during the execution of the method. This implementation of the BAdIs complements the Business Transaction Event 1650 described in the second example. You can also use the FB03 transaction to display receipts in the same way that you implement the FB03 filter. In this case, implement the required checks in the BAdI FI_AUTHORITY_ITEM.
If you get into the situation that authorizations are required that were not considered in the role concept, "Shortcut for SAP systems" allows you to assign the complete authorization for the respective authorization object.
For communication between SAP systems, you should use HTTPS if you think the data transfer could be intercepted.
To do this, search within the personnel data for a personnel number that entered this user ID in the System User Name SAP System (0001) subtype of the Communication (0105) info type.
