Calling RFC function modules
Maintenance Status
In many distributed organisations, the Profit Centre is used to map out the distributed units. However, this was only possible for FI with additional programming. In integrated data flows in SAP ERP, the sending application usually does not check the authorization objects of the receiving application. Financial Accounting (FI) in SAP does not check permissions for cost centres and profit centres. However, depending on the case of use, this may be necessary, e.g. if distributed entities are to operate as small enterprises within the enterprise and only collect and view data for this particular unit at a time. With the introduction of the new general ledger, SAP has technically merged the financial accounting and the profit centre account, so that the question of the inclusion of profit centre allowances in FIs becomes even more important.
This start authorization check is delivered inactive. To use it, you must activate it. After activation, you can use authorizations to control which Web Dynpro ABAP applications users are allowed to run. For the start authorization check of Web Dynpro ABAP applications, the system uses the authorization object S_START in the same way as the authorization object S_TCODE for transactions. The object has the fields AUTHPGMID, AUTHOBJTYP and AUTHOBJNAM, which correspond to the key fields PGMID, OBJECT and OBJ_NAME of the object catalog (table TADIR). So, during the start authorization check, the Web Dynpro ABAP runtime checks the key of the object catalog entry for the Web Dynpro ABAP application.
Use usage data for role definition
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.
You should therefore enforce cryptographic authentication and communication encryption by setting up Secure Network Communication (SNC). SNC provides a strong cryptographic authentication mechanism, encrypts data transmission, and preserves the integrity of the transmitted data. For some time now, SNC is freely available without a SSOMechanism (SSO = Single Sign-on) for SAP GUI and the RFC communication of all SAP NetWeaver customers. You should always implement SNC between SAP GUI and application server, as this communication can also run over open networks. For RFC communication, you need an SNC implementation if you think the data transfer could be intercepted.
"Shortcut for SAP systems" is a tool that enables the assignment of authorizations even if the IdM system fails.
If you want to set up a constraint on AIS users to specific audit structures or protect individual audits from access, you can use the S_SAIS authorization object.
However, if there are open permission fields in a permission, they will not be combined unless all permission fields in the permission values are the same.
