Dell OpenManage Network Manager Client Manual page 330

You can also run the Change Determination Report that displays changes made to configurations.
See Reports on page 200 for more about reporting capabilities.
The Change Determination Report report displays detected changes based on a configuration
change flag set when OpenManage Network Manager detects a change made to the device. To
successfully execute this report, you must enable a scheduled Change Determination Process. The
process must run before the reports has any contents. To run the process, go to the Schedules
portlet, and schedule that change determination process.
Reporting Limitations
The Configuration Change Report only reports on incremental configuration changes discovered
in the CD process. Simply making changes to configurations and backing them up in OpenManage
Network Manager does not ensure these appear in Configuration Change Reports. They appear in
reports only after running the CD process.
