#UI Policiesare the best way to implement dynamic form behavior such asmaking fields mandatory, hiding
/showing fields, and setting values based on conditions.
Making "Resolution Code" mandatory when "State" is changed to "Resolved" This requires aUI Policythat:
Condition:State = Resolved
Action:Set "Resolution Code" field toMandatory = True
Hiding the "Major Incident" checkbox unless the logged-in user has the "Major Incident Manager" role This requires anotherUI Policythat:
Condition:User does NOT have the rolemajor_incident_manager
Action:Hide the field
Option A (Dictionary Design)
The dictionary defines the structure of fields butdoes not control dynamic form behaviorlike field visibility or conditions.
Option B (Field Limiter)
There is no such feature called "Field Limiter" in ServiceNow.
Option D (UI Design)
"UI Design" is not a recognized concept in ServiceNow.UI Policiesare used for form behavior changes.
Option E (Form Constraint)
There is no "Form Constraint" feature in ServiceNow; ACLs and UI Policies control field behavior instead.
