Conclusion and outlook
A concept for SAP authorizations prevents system errors and DSGVO violations
You can use the BAdI SMIME_EMAIL of the SMIME extension spot and implement the CERTIFICATE_RETRIEVAL and CERTIFICATE_SELECTION methods according to your requirements. This BAdI is called whenever an encrypted e-mail is sent. An extension allows you to search for a valid certificate at run time (for example, the one with the longest validity) to the recipient's email address in a source you defined. In the default implementation, the BAdI searches for the certificate in the Trust Manager's address book. For details on the availability of BAdIs, see SAP Note 1835509.
Regardless of whether you select the degree of simplification COARS = 1 or 2, you should not enter * or SAPDBPNP (programme name of logical database PNP) in the REPID field. With these values, you allow access to the logical databases SAPDBPNP and SAPDBPAP and thus to all contained root data.

Security notes correct vulnerabilities in SAP standard software that can be exploited internally or externally. Use the System Recommendations application to keep your systems up to date. SAP software is subject to high quality assurance standards - however, security vulnerabilities may occur in the code. These vulnerabilities can, in the worst case scenario, open the door to external and internal intruders. It is not difficult to find guidance on exploiting these vulnerabilities in relevant internet forums. A permission concept is only as good as the code that performs the permission checks. If no permission check occurs in your code, the permission concept cannot restrict access. For these reasons, SAP has introduced Security Patch Day (every other Tuesday of the month), which will allow you to better plan for implementing the security advisories. In addition, you can use the System Recommendations application in the SAP Solution Manager to get a detailed, cross-system overview of the security advice you need. The system status and the SAP hints already implemented are taken into account. With this support, ensure that your system landscape is at the current security level.
The possibility of assigning authorizations during the go-live can be additionally secured by using "Shortcut for SAP systems".
The website "www.sap-corner.de" offers a lot of useful information about SAP authorizations.
