Where can you find information about when the productive SAP HANA system was updated and to which version?

The correct source for finding information about when the productive SAP HANA system was updated and to which version is the catalog view of the SAP HANA Web-based Development Workbench. This view provides detailed information about the system, including version information, which is crucial for monitoring and managing systems effectively.

When utilizing the catalog view in the Web-based Development Workbench, administrators can ascertain not only the version but also the specific updates that have been applied to the system. This facilitates efficient tracking and management of the software, ensuring that the system is up-to-date and running optimally.

Other options, such as the administration editor of the SAP HANA studio and the system log files, do provide various forms of system information, but they are not the preferred locations for tracking version updates in a clear and user-friendly manner. Similarly, while the support status overview is useful for assessing the overall health and support status of the system, it does not specifically detail update histories or version changes directly.
