A concept for SAP authorizations prevents system errors and DSGVO violations
Starting Web Dynpro ABAP applications
Developer and customizing authorizations represent a great potential danger in productive SAP systems. Here, authorizations must be assigned very restrictively, e.g. only to emergency users. The same applies to RFC connections from a development system to productive systems. Such connections can only be used to a very limited extent.
Do you also work in a complex system landscape where roles are decentralised? Then, inconsistencies can occur by transporting profiles from different systems to a target system. We'll show you how to prevent that. In the case of decentralised maintenance of eligibility roles, i.e. maintenance of roles in different systems or clients, there is a risk that the number sequences for the generation of eligibility profiles overlap. You can then generate profiles with the same name for different roles in different clients. As soon as you transport these eponymous permission profiles into a common target system, the profile will be overwritten by the newly imported profile and inconsistencies will arise. As a result, you may, for example, assign an ERP Permissions Role an SCM permission profile. This may result in a user assigned the ERP role not obtaining the required permissions or even too many permissions. You also have a problem if you want to use the permission profile to determine the source system and the client in which this profile was generated. This is not possible if the first and third characters of the SAP System ID (SID) and the number sequence for generating the permission profile match.
Dissatisfaction and unclear needs in the process
You know that changing your SU24 data involves mixing the roles in question. Previously, the permission administrators had to select roles from, for example, the SUIM transaction to edit them. Often, the remixing of the respective roles is also forgotten. In order to ensure that you can set the mixing mode for the respective roles directly when maintaining the data in the transaction SU24, the function has been provided here with the respective support packages named in SAP Note 1896191. Correction is used to change the mixing mode for PFCG: On/Off/Roles. The function assigns the shuffle mode to the roles, which corresponds to step 2c of the transaction SU25 (see tip 43, "Customise Permissions After an Upgrade"). You can enable this function by using the value Y for the parameter SU2X_SET_FORCE_MIX in the table PRGN_CUST. The status of the mixing mode can be checked by clicking the button Mixing mode for PFCG: Enquire On/Off. By default, this feature is off. The Roles button (Use in Single Roles) identifies all the roles that the selected application contains and displays them directly in the SU24 transaction. You will receive a list of all matching roles in the SUPC transaction by selecting the Also-to-be-matched roles option, and you can now gradually update the roles.
SNC secures communication with or between ABAP systems, but there are also many web-based applications in SAP system landscapes. They communicate via the Hypertext Transfer Protocol (HTTP). The data is also transmitted unencrypted when communicating via HTTP; Therefore, you should switch this communication to Hypertext Transfer Protocol Secure (HTTPS). HTTPS uses the encryption protocol Transport Layer Security (TLS) for secure data transfer on the Internet. You should therefore set up HTTPS for all users to access the Web. For communication between SAP systems, you should use HTTPS if you think the data transfer could be intercepted. You should either set up HTTPS on individual components of the infrastructure (such as proxies), or the ABAP systems should support HTTPS or TSL directly. Details of the configuration can be found in the SAPHinweis 510007.
"Shortcut for SAP systems" is a tool that enables the assignment of authorizations even if the IdM system fails.

To do this, assign permissions to the K_KEPL_BER object.

In integrated data flows in SAP ERP, the sending application usually does not check the authorization objects of the receiving application.
