Explanation
These are some of the main characteristics of the Logon ticket throughout an SSO logon procedure. SSO (Single Sign-On) is a feature that enables users to log on to multiple systems or applications with one authentication process and without entering their credentials multiple times. Logon ticket is one of the methods for implementing SSO in SAP systems, which uses digital certificates and cookies to authenticate users and systems. The Logon ticket is used for user-to-system communication, which means that it contains information about the user's identity and authorizations that can be verified by the target system or application.
The Logon ticket session is held in the working memory, which means that it is stored temporarily in the memory of the user's browser or system and deleted when the session ends or expires. References:

These are some of the characteristics of the SAP_INTERNAL_HANA_SUPPORT catalog role in SAP HANA systems. A catalog role is a role that is predefined by SAP HANA and stored in the _SYS_REPO schema of the system database. The SAP_INTERNAL_HANA_SUPPORT catalog role is a special role that is used for internal support purposes by SAP employees or authorized partners.
