A concept for SAP authorizations prevents system errors and DSGVO violations
Do not assign SAP_NEW
You assign a reference user to a dialogue user by registering the reference user for additional rights in the SU01 transaction on the Roles tab in the Reference User field. If you are using Central User Administration (ZBV), the assignment applies to all connected systems. If the reference user does not exist in one of the systems, the mapping is ignored. However, the use of reference users also creates risks. This makes it easier to summarise permissions because it is difficult to keep track of the assigned permissions. In SAP NetWeaver AS ABAP 7.0 and above, reference users are considered in the reports of the user information system.
In contrast to storing passwords in the form of hash values, the user ID and password are transmitted unencrypted during the login of the client to the application server. The Dynamic Information and Action Gateway (DIAG) protocol is used, which may look somewhat cryptic but does not represent encryption. In addition, there is no cryptographic authentication between the client and the application server. This applies not only to communication between the user interface and the application server, but also to communication between different SAP systems via Remote Function Call (RFC). So, if you want to protect yourself against the access of passwords during the transfer, you have to set up an encryption of this communication yourself.
Copy values from the Clipboard to the transaction's PFCG permission fields
This very critical authorization can be used to electronically erase, or manipulate program runs including authorization queries in a variety of ways. This authorization should be assigned only very restrictively, for example developers need the authorization however for their daily work.
SAP Note 1854561 provides a new possible value for the auth/authorisation_trace parameter: F (Trace enabled with filter). Allows you to limit the permission trace to values that can be set by the filter. The filters are defined in the STUSOBTRACE transaction (see SAP Note 1847663).
With "Shortcut for SAP systems" you can automate the assignment of roles after a go-live.
Understanding the structure and functioning of the system is especially important for IT administration. It is not for nothing that "SAP Basis Administrator" is a separate professional field. On the page www.sap-corner.de you will find useful information on this topic.
These applications must therefore be included in the PFCG rolls.
So much information... how can you keep it so that you can find it again when you need it? That's what Scribble Papers is great for.
This process ultimately ensures that users only have the authorizations in the SAP® system that they actually need.
