Prevent excessive permissions on HR reporting
Apply User Management Solutions in SAP HANA
Reference users are not intended to access an SAP system, but are used for authorisation administration and therefore always have a disabled password. Reference users inherit the permissions assigned to them to the users with whom the reference user is registered. For this purpose, the user buffer of the reference user is also created at login and these entries are also checked during permission checks of the inheriting user.
Now the SAP system is basically able to encrypt emails. However, the system still lacks the recipient's public key. You can manage the required public key information in the Trust Manager's address book. You can find the address book in the Transaction STRUST menu under Certificate > Address Book. Here you can import individual certificates by selecting the corresponding certificate in Certificate > Import Certificate. To get the certificates for all relevant users in this address book via a mass import, use the example programme Z_IMPORT_CERTIFICATES appended in SAP Note 1750161 as a template for a custom programme.
Application Permissions
With the SAP NetWeaver 7.03 and 7.30 releases, Web Dynpro ABAP applications (as well as other Web Dynpro ABAP functions, see SAP Note 1413011) have been tested for permission to launch such applications. The authorization object that controls this startup permission is S_START. This authorization object is used in the same way as the S_TCODE authorization object.
Run the System Trace for Permissions (ST01 or STAUTHTRACE transaction) to record permission checks that you want to include in the role (see Tip 31, "Optimise Trace Evaluation"). Applications are logged through the Launch Permissions checks.
Assigning a role for a limited period of time is done in seconds with "Shortcut for SAP systems" and allows you to quickly continue your go-live.
So you need the opportunity to see for yourself.

Safeguard measures: Lock down the user, change the password, assign it to the SUPER user group and log it with the Security Audit Log.
