Features of the SAP authorization concept
In particular, you can derive valuable information about customer transactions, since experience has shown that not all transactions are used. In this context, it is important to mention that you should only use the usage data logged and extracted from the SAP system for the optimisation of SAP role concepts. This information may only be used with the involvement of a co-determination body of your organisation, since this information can of course also be derived from individual users for performance control purposes. However, experience has shown that the use of these data with an early involvement of the institutions of codetermination and the definition of earmarks is uncritical.
Employees should only be able to access data relevant to their work, country or accounting area in tables? Set up organisational criteria to ensure this. Do you want users to be able to read or maintain specific tables, but only have access to the table contents that are relevant to them? The S_TABU_DIS and S_TABU_NAM permissions objects allow you to access the tables, but if you want a user to see or maintain only parts of the table, these authorization objects will reach their limits.
Customise evaluation paths in SAP CRM for indirect role mapping
Do you need to integrate the S_TABU_NAM authorization object into your existing permission concept? In this tip, we show you the steps that are necessary to do this - from maintaining the suggestion values to an overview of the eligible tables. You have added the S_TABU_NAM authorization object to your permission concept, so that users can access the tables not only through the S_TABU_DIS authorization object, but also through S_TABU_NAM. This directly regulates access to the tables via table permission groups or, if access is not allowed through table permission groups, via the table permission (see Tip 73, "Use table editing authorization objects"). Do you want to identify the tables or created parameter transactions that allow access to only specific tables to maintain SU24 for these suggested values in the transaction? This makes it easier to maintain PFCG roles. Furthermore, a tool would be useful to give you an overview of the tables for which a user is entitled.
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.
With "Shortcut for SAP systems" you can automate the assignment of roles after a go-live.
When you create users in the SU01 transaction, do you want to automatically pre-occupy certain fields from a data source? Use a new BAdI for which we present an implementation example.
