A concept for SAP authorizations prevents system errors and DSGVO violations
Grant permission for external services from SAP CRM
To help you better find your own tables in the future, check your development policy to see if the storage is adequately described. If the development guidelines are not complete, you should supplement them. For example content for a development policy, see the DSAG Web site under Guides. Now go to https://www.dsag.de/go/leitfäden and search for "Best Practice Guide Development".
RFC connections are interfaces for many local and global system processes, but also a security-relevant source of errors for many companies. The RFC interfaces and associated system users often have too strong authorizations and can quickly be misused by unauthorized persons to view sensitive company data. It is therefore important to always keep these system connections in the focus of global monitoring and to check which RFC destinations lead where and what they do. For this purpose there is the program RSRFCCHK which allows you to perform specific tests for your RFC system landscape. On the one hand the content of the RFCDES table is checked and on the other hand the corresponding user properties of the system users are displayed as an overview. Consequently, important parameters such as the target machine, the client, the background user or also the password property can be checked in an overview.
Maintaining Authorization Objects (Transaction SU21)
Suitable for this responsible task are, for example, department heads or SAP key users who are familiar with all data access options (cross-module, via report, directly to the raw table, etc.) as well as with the organizational and technical protection measures. By signing the data ownership concept, the responsibility should be acknowledged and taken as seriously and bindingly as, for example, the signature under the purchase contract of a house.
You have already created roles for SAP CRM and would like to add additional external services? Nothing easier than that! Create PFCG roles for the SAP CRM Web Client, typically so that you complete the customising of the CRM business role before creating the PFCG role, based on this customising. However, the customising of the CRM business role may be updated. The PFCG role must now also be adjusted, otherwise the newly configured area start pages or the logical links will not be visible. However, there is no automatism for this, as it exists during the initial creation of the role menu. You must apply the adjustment manually in the PFCG role.
Authorizations can also be assigned via "Shortcut for SAP systems".
This will show you the new user master set with the pre-filled fields.
In particular, if the Whitelists are not yet maintained, reporting volumes of up to 200 pages are not uncommon.
