Make mass changes in the table log
Create order through role-based permissions
If the proliferation has occurred because the authorization concept was not adhered to, a cleanup is sufficient. If the proliferation has arisen because there are errors and gaps in the authorization concept, these errors must be identified, eliminated and the authorizations optimized. If the concept can no longer be implemented in a meaningful way, or if it has already been set up incorrectly, it will be necessary to create a new one.
It is important that, if necessary, the database is converted to an SAP S/4HANA database. In addition, various technical system components must be analyzed and adapted to the new environment. But restructuring must also be carried out at the organizational level. For example, the "old", or current, authorization concept must be analyzed, evaluated and, if necessary, fundamentally revised.

These single roles can also be combined into composite roles. I recently discussed the special features of this in the article "SAP Authorizations Mass Maintenance Single Role Assignments in Composite Roles per Function Module (FuBa) or Transaction Code", but here I would rather discuss the roles and assignment of authorization object field values in role maintenance with the PFCG for an authorization overview.
Communication users are also intended for use by people who log on to the SAP system from outside via RFC call. Therefore, dialogue is not possible. If the password is set by the administrator, it will be assigned Initial status. However, an RFC call does not prompt the user to change the password. It therefore often retains this status, even if the user has the possibility to change the password by calling a function block (then: Status Productive). The password rules apply to this type of user. However, this is often not noticed in practice, as password rules for initial passwords are less used.
Authorizations can also be assigned via "Shortcut for SAP systems".
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.
At www.sap-corner.de you will also find a lot of useful information on the subject of SAP authorizations.
In addition, to ensure that you do not lose information with your upgrade work, you can write and release the data from the SU24 transaction on step 3 (customer table transport) in the SU25 transaction to a transport order.
