Use automatic synchronisation in central user management
SAP Authorizations - A Common Perspective of Developers and Consultants
Help, I have no permissions (SU53)! You want to start a transaction, but you have no permissions? Or the more complex case: You open the ME23N (show purchase order), but you don't see any purchase prices? Start transaction SU53 immediately afterwards to perform an authorization check. The missing authorization objects will be displayed in "red". You can also run SU53 for other users by clicking on Authorization Values > Other Users in the menu and entering the corresponding SAP user name.
It takes too long to read out the User and Permissions Management change notes? With a good archiving concept, you can improve performance. User and Permissions Management applications write change documents that increase significantly over time and can cause long wait times to read them. To reduce waiting times, you should archive the documents and set a logical index for key change documents. For this, however, you need a comprehensive overview of the storage locations and also of the evaluation possibilities and archiving scenarios. In the following we will show you how you can optimise the change document management of the user and permission management.
Default permissions already included
Custom programmes should be protected with permissions, just like standard applications. What rules should you follow? Introductory projects usually produce a large number of customised programmes without being subjected to a permission check when they are executed. For your programmes, you should create custom permissions checks by default and manage them accordingly.
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.
Assigning a role for a limited period of time is done in seconds with "Shortcut for SAP systems" and allows you to quickly continue your go-live.
For example, for the Controlling division, the connection to the Finance division is first established by connecting the accounting area (FI) to the cost accounting area(s).
Your SAP system contains a lot of data, which is often confidential.
