AUI Policyis the preferredno-codeapproach in ServiceNow to dynamically control themandatory, read-only, or visibilitystate of form fields based on specified conditions. Unlike Client Scripts, which require JavaScript coding, UI Policies provide aneasy-to-configure, rule-based solution.
They allow administrators tocontrol form behaviorwithout scripting.
They arefaster and more efficientthan Client Scripts.
Theyrun on the client-side, meaning changes occur dynamically as users interact with the form.
Defineconditions(e.g., " Priority is High " ).
Setactions(e.g., make " Due Date " mandatory, read-only, or hidden).
Apply the UI Policy to the form automatically when the condition is met.
A). UI Action# UI Actions create buttons, links, or context menu items; they do not control form fields.
B). Client Script# While Client Scripts can achieve similar functionality, they require JavaScript coding, making them alow-coderather than ano-codesolution.
C). UI Script# UI Scripts are reusable JavaScript libraries, not designed for controlling form fields.
D). UI Rule# No such feature exists in ServiceNow.
