FIELD (Workflow) element

You use the FIELD (Workflow) element to specify the rules and conditions that apply to a field during a state change or workflow transition. The rule is applied based on where the FIELD (Workflow) element appears under the STATE, TRANSITION, DEFAULTREASON, or REASON element of which its parent FIELDS element is a child. To learn more, see Q: Where should I apply a field rule?

Note

For information about the FIELD (Definition) element, which you use to define fields for a type of work item, see FIELD (Definition) element reference.
