A customer has asked for the following updates to a form: Make Resolution code mandatory, admin state is changed to Resolved. Hide major incident check box, unless logged in user has Major incident Ma

"Dictionary Design" refers to configuring field properties directly within the dictionary, such as default mandatory status, which is not conditional based on other field values or roles.

"Field Limiter" is not a standard ServiceNow feature or rule type for implementing conditional form logic.

UI Policies are used to dynamically change the behavior of form fields, such as making them mandatory, visible, or read-only based on specific conditions or user roles. This directly addresses making the "Resolution code" mandatory when the state changes and hiding the "major incident check box" based on a user's role.

"UI Design" is a broad term referring to the overall layout and aesthetics of the user interface, not a specific rule type for conditional field behavior.

"Form Constraint" refers to any rule or validation mechanism that imposes restrictions or behaviors on fields within a form. UI Policies are a specific type of form constraint that helps enforce these conditions dynamically on the client-side, like making fields mandatory or controlling their visibility.
