Ensuring secure administration
Full verification of user group permissions when creating the user
Do you need to integrate the S_TABU_NAM authorization object into your existing permission concept? In this tip, we show you the steps that are necessary to do this - from maintaining the suggestion values to an overview of the eligible tables. You have added the S_TABU_NAM authorization object to your permission concept, so that users can access the tables not only through the S_TABU_DIS authorization object, but also through S_TABU_NAM. This directly regulates access to the tables via table permission groups or, if access is not allowed through table permission groups, via the table permission (see Tip 73, "Use table editing authorization objects"). Do you want to identify the tables or created parameter transactions that allow access to only specific tables to maintain SU24 for these suggested values in the transaction? This makes it easier to maintain PFCG roles. Furthermore, a tool would be useful to give you an overview of the tables for which a user is entitled.

If you have defined the roles to the extent that the essential processes are depicted, then you will technically check which organisational features they contain (organisational levels, but also cost centres, organisational units, etc.). You then compare the technical result with the result from the consideration of the structure organisation and the business role description. A likely result is that you do not have to use all technical organisational features for differentiation. A possible result is that you want to add fields such as the cost centre to the organisation level.
Limitations of authorization tools
In the beginning, the FI and CO modules were separated from each other. Both modules have been combined by SAP as higher-level modules in the accounting area. The main reason for this is the tight process structure, which enables a smooth transition between the two modules. As a result, SAP FI and CO now only appear as the joint module SAP FICO.

Note that the SAP_NEW_ individual profiles should be retained themselves, so that at any given time, traceability is ensured as to which release and which permission was added. For more information, see SAP Notes 20534, 28175, and 28186. SAP Note 1711620 provides the functionality of an SAP_NEW role that replaces the SAP_NEW profile. If you have added this note, the profile will no longer be used. Instead, you can generate your PFCG role SAP_NEW by using the REGENERATE_SAP_NEW report. When you call the report, in the source and target release selections, type in the appropriate fields, and the role is created for that release difference.

During go-live, the assignment of necessary authorizations is particularly time-critical. The "Shortcut for SAP systems" application provides functions for this purpose, so that the go-live does not get bogged down because of missing authorizations.

In addition, you have created a transparent way to document for which applications your customer's permissions are available.

The following actions are subject to authorization checks that take place before a program or table maintenance is started and cannot be bypassed by SAP applications: Start of transactions (authorization object S_TCODE) - Start of Web Dynpro applications (authorization object S_START) - Start of reports (authorization object S_PROGRAM).
