About Property rules

The standard properties in the History- base class support the work item history and rule history processing.

This table identifies several of these, in alphabetical order ignoring the first two characters of the name. Many properties are present only in history records of specific classes or types.

Properties marked (Read-only) are computed by standard rules; don't set values for these properties in your application rules except in unusual situations where you intend to override the default computation.
