Application Permissions
Immediate authorization check - SU53
If the proliferation has occurred because the authorization concept was not adhered to, a cleanup is sufficient. If the proliferation has arisen because there are errors and gaps in the authorization concept, these errors must be identified, eliminated and the authorizations optimized. If the concept can no longer be implemented in a meaningful way, or if it has already been set up incorrectly, it will be necessary to create a new one.
The case that the user buffer is not up to date is very rare. The auth/new_buffering profile parameter sets the value 4 to immediately update the permissions, i.e. changes to the user root or roles or profiles, and write them to the USRBF2 database table without requiring a new login. This value is set by default. The fact that the buffer is not up-to-date is recognised by the fact that existing permissions that are not in the buffer are marked in the transaction SU56 with the note "In the root data but not in the user buffer".
Testing Permission
The SAP authorization concept ensures that no unauthorized access can be made to transactions, programs and services in SAP systems. To call up business objects or execute transactions in the SAP system, a user therefore requires the appropriate authorizations. When called, the application started via a transaction checks whether the authorization exists and whether the user is allowed to perform the selected operation.
If you want to understand how to run a permission check in your code, you can use the debugger to move through the permission check step by step. To implement your own permission checks, it may be helpful to see how such checks have been implemented in the SAP standard. In this tip, we show you how to view the source code of permission checks using the debugger in the programme, or how to get to the code locations where the permission checks are implemented.
For the assignment of existing roles, regular authorization workflows require a certain minimum of turnaround time, and not every approver is available at every go-live. With "Shortcut for SAP systems" you have options to assign urgently needed authorizations anyway and to additionally secure your go-live.

The Security Audit Log (SAL) has ten different filters in the current releases, which control which events are logged.
The freeware Scribble Papers is a "note box" in which all kinds of data can be stored. It takes in typed texts as well as graphics and entire documents. The data is then organised in folders and pages.
The authorization concept must therefore be flexible enough to allow future changes in the organization to be implemented quickly and in compliance with the rules.
