The SAP authorization concept
RSUSR003
This function was not part of the standard delivery. With the support package named in SAP Note 1860162, the transaction SAIS_SEARCH_APPL is now delivered. This transaction allows you to verify that other applications have startup properties similar to those available in a particular application. For example, we searched for applications with similar functionality as the PPOME transaction provides.
To do this, first define what information should be checked. In the SU20 transaction, verify that the required fields may already exist as permission fields. If you want to check custom fields, you must create your own permission fields in the transaction SU20. Please pay particular attention to the (F4) help provided. When defining customised permission fields, you assign a name in the Field Name field that is in your Customer Name Room and assign the corresponding data element and, if desired, a table name for a value help. The next step is to create your own authorization object and assign your permission fields and, if necessary, default permission fields. If you use the ACTVT field to validate the activity, you must use the Activities allowed button to select the activities that you want to validate from the source code of your programme. For recommendations on the naming conventions for authorization objects, see SAP Note 395083.
Introduction & Best Practices
If you have developed your own permission checks to use them in your own programmes or to make extensions to the SAPS standard, it is essential that you maintain the Z authorization objects as suggestion values for the respective applications. Thus, they do not have to be reworked manually in the respective roles. In addition, you have created a transparent way to document for which applications your customer's permissions are available. Last but not least, a well-managed suggestion value maintenance helps you with upgrade work on suggestion values and PFCG roles. This ensures that your changes and connections to the respective PFCG roles are retained and new permissions checks for the new release are added to the applications.
Which authorization data does a role have (PFCG)? Again, start the transaction PFCG and display a role. Then branch to the tab Authorizations and click on the button with the "glasses" (bottom left): Display authorization data.
Authorizations can also be assigned via "Shortcut for SAP systems".
This report checks the customising of the CRM business role for which the PFCG role is to be created, and writes all area start pages and logical links to a text file in the form of external services.

As described in Tip 43, "Customising Permissions After Upgrading," administrators may see some upgrade work as a black box.
