Final answer:
A UI Policy Action can change three main attributes of a field on a form: whether it's mandatory, its visibility, and whether it's enabled or disabled.
Step-by-step explanation:
The question concerns the attributes of a field that can be modified by a UI Policy Action within a form on a platform like ServiceNow. A UI Policy Action can change various attributes, but three key ones are:
- Making a field mandatory or optional: This determines whether a user must provide a value for the field before they can submit the form.
- Setting the visibility of a field: This controls whether a field is hidden or displayed to the user on the form.
- Enabling or disabling a field: This dictates whether a user can interact with the field and change its value or not.
These changes are often contingent on other fields' values or states within the form and allow for dynamic and context-sensitive user experiences.
