Immediate authorization check - SU53
Preventing sprawl with the workload monitor
In addition to defining permissions for external RFC access through the S_RFC authorization object, it is possible to prevent external calls to function blocks. From SAP Net-Weaver AS ABAP 7.40 there is the additional SAP Unified Connectivity (UCON) layer. It controls external access to RFC function blocks independently of users or roles and can be configured to suit your needs. All function modules that are to be executable via RFC are entered into the UCON Communication Assembly. If a function block is not stored there, the call will be blocked. UCON has been designed to minimise impact on RFC call performance. The necessary function blocks are identified in the UCON Phase Tool (transaction UCONPHTL), which constantly monitors all external RFC calls and supports an introduction of the UCON Communication Assembly. This allows calls to new function blocks (such as custom developments, support package changes) to be analysed and, if necessary, released for external access. In addition, UCON offers the possibility to review the configuration in an evaluation phase. There are approximately 40,000 RFC-enabled function blocks in an ERP system; Usually no more than a few hundred of them are used. With the use of UCON you therefore increase the security of your system.

Depending on your SAP NetWeaver release status, you must include SAP Note 1731549 or a support package. After that, it is no longer possible to create new users whose names consist only of variants of spaces or non-visible special characters. Changes to existing users are still possible. The customising switch BNAME_RESTRICT, also included in SAP Note 1731549, allows you to control whether you want to allow alternate spaces at certain locations of the user ID.
Check the SAP authorization concept
A major advantage of SAP SuccessFactors is flexibility. Different project teams can implement and use several modules, processes or add-ons in a short time. The processes can be optimized again and again. A central basis for extensively digitized processes are structured specifications that regulate system access and control access rights. In this context, SAP offers the concept of role-based authorizations. Role-based SAP authorizations grant different groups of people different options for action and views in the system, e.g., regulate access to salary data. Role-based authorizations are flexible and facilitate global implementations of SAP SuccessFactors, e.g. in different national companies. Once implemented, roles and their authorizations can be quickly rolled out to the new region. The roles do not have to be completely reconfigured each time. Slight adjustments are all that is required.

The first step is to create an IMG project. You can create a new project or edit an existing project to create a customising role. To do this, call the SPRO_ADMI project management entry transaction. If a suitable project is not available, you can view the list of SAP customising activities. To do this, click the SAP Reference-IMG button or create a new project. To do this, select the Create Project button ( ) or the (F5) button. A new window will open, where you enter the project name. Note that you have a maximum of ten characters for the name. Once you have confirmed your input, a new screen will open. The General Data tab allows you to specify users, project managers, project times, and the language for the information texts.

The possibility of assigning authorizations during the go-live can be additionally secured by using "Shortcut for SAP systems".

You can also use the trace to search only for permission errors.

A note box in which data of all kinds can be quickly filed and retrieved. This is what Scribble Papers promises. At first, the program looks very spartan. But once a small structure is in place, you realise the great flexibility of this little helper.

If you use the ACTVT field to validate the activity, you must use the Activities allowed button to select the activities that you want to validate from the source code of your programme.
