The Update Versions `[sys_update_version]` table contains records that
represent the state of a customizable object at a particular time.
A customizable record is any object that is tracked by Update Sets, such as business rules
or script includes. A new version record is created automatically whenever a user changes a
customizable record or changes the application file for the customizable record.

A record represents the version of a
base system object as it was delivered in the most recent upgrade. Baseline versions are
created only for objects that have been modified by a user, and they are updated each time
the system is upgraded.
