Consulting firms adjust the roles and authorizations in retrospect. This usually means "making the best of it" and making ad hoc adjustments - in other words, not fixing the root cause and cleaning up from scratch. Companies should therefore ask themselves: how can this be avoided? What requirements must a DSGVO-compliant authorization concept fulfill? How can we remain meaningful regarding the authorizations of specific individuals in the system and the purpose of the authorizations?
The background to the mass presence of authorization objects in a PFCG role after a role menu has been created is usually the mass of generic OP links that are not actually necessary for the CRMBusiness role. The existence of proposed values from the transaction SU24 loads the proposed authorisation values associated with the respective external services into the PFCG role, which results in too many unnecessary authorization objects being placed there. By excluding the GENERIC_OP_LINKS folder, you only need to take care of the external services and their authorization objects configured in the CRM business role in your PFCG role. For a user to have all the necessary permissions, you now assign the basic role with the permissions to the generic operating links and the actual role that describes the user's desktop.

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.
Critical permissions are permissions that allow you to view or modify security-related configurations in the SAP system, or perform activities that are critical from a legal or business perspective. This also includes access to sensitive data, which are e.g. personal. Critical permissions are really critical in themselves and pose a risk only if they get into the wrong hands. In any case, when using critical permissions, you should observe the principle of restricting rights. There are no general definitions of risk; Therefore, each company should define the compliance requirements for itself. Identifying critical SAP permissions is an important task and should be performed in every company. Particular attention should be paid not only to the award of transactions but also to the value characteristics of each of the eligible objects. It is important to mention that preventive regular inspections do not have to be burdensome. However, they will lead to greater transparency and security.
