Solution approaches for efficient authorizations
Authorization roles (transaction PFCG)
Confidential information from your SAP system can also be sent by email. Make sure that this data is only transmitted encrypted. Your SAP system contains a lot of data, which is often confidential. This can be business-critical or personal data or even passwords. It happens again and again that such data must also be sent by e-mail. Therefore, make sure that this information is always encrypted and signed if necessary. Encryption is intended to ensure the confidentiality of the data, i.e. that only the recipient of the e-mail should be able to read it. The digital signature serves the integrity of the data; the sender of an e-mail can be verified. We present the configuration steps required for encryption and provide examples of how to encrypt the sending of initial passwords. There are two ways to encrypt and sign emails in the SAP system: via SAPconnect, via a secure third-party email proxy.

Depending on your SAP NetWeaver release status, you must include SAP Note 1731549 or a support package. After that, it is no longer possible to create new users whose names consist only of variants of spaces or non-visible special characters. Changes to existing users are still possible. The customising switch BNAME_RESTRICT, also included in SAP Note 1731549, allows you to control whether you want to allow alternate spaces at certain locations of the user ID.
Existing permissions
Once you have defined your criteria for executing the report, you can create different variants for the report and schedule corresponding jobs to automatically lock down or invalidate the inactive users. If you want to start the report in a system that is connected to a Central User Management, you should consider the following points: You can only set local user locks. You can set the validity period only if the maintenance is set to Local in the settings of the Central User Management (this setting is set in the SCUM transaction).

If you manage your SAP system landscape via the Central User Administration (ZBV), you must insert SAP Note 1663177 into both the ZBV system and all attached subsidiary systems. In this case, also note that the default user group will be assigned in the daughter systems if no user group has been distributed during the user's installation from the ZBV. In addition, you will receive an error message in the SCUL transaction stating that a user group must be assigned to the user (via the ZBV headquarters). This behaviour is independent of the settings of the distribution parameters for the user group in the SCUM transaction. If you have set the distribution parameters for the user group to Global or Redistribution, the appropriate subsidiary system will reject the changes made to users that do not have a user group in the Central System, and you will receive an error message in the SCUL transaction.

However, if your Identity Management system is currently not available or the approval path is interrupted, you can still assign urgently needed authorizations with "Shortcut for SAP systems".

To implement the BAdIs, use the transaction SE18; there you can also see the example class CL_EXM_IM_IDENTITY_UPDATE.

In the SAP system, you can create derived roles for specific fields in authorization objects.
