Following are few important column details:

The standard properties in the History-Work- class support the work item history display from the History button ().

This table identifies several of these, in alphabetical order, ignoring the first two characters of the name. Many properties are present only in work history records of specific types. Properties marked () are computed by standard rules. Do not set values for these properties in your application rules, except in unusual situations where you intend to override the default computation.
