E. Setting fields mandatory

UI Policies canenforce mandatory fieldsbased on conditions.

A. Setting fields to accept the data with ‘n’ number of characters

Field length restrictions are set in theDictionary Definition, not UI Policies.

C. Setting fields to accept the data in an expected format

Data formatting (e.g., date, phone number) is controlled byField Types and Data Policies, not UI Policies.

InServiceNow Access Control Definitions, permissions for a table can be set usingAccess Control Rules (ACLs), which define who cancreate, read, update, and delete (CRUD)records. Permissions can be applied using:

Roles

Roles(sys_user_role) control access by grouping users with similar permissions.

Example: An ACL rule can specify that only users with theitilrole can view incidents.

Script that sets the answer variable to true or false

Customscripts(written in ACL conditions) determine access dynamically.

Example: A script may check if the logged-in user is therecord's assigned userbefore granting permission.

Conditional Expressions

Conditional expressions allowrule-based accesswithout scripting.

Example: A condition like"Assigned to is the current user"can be used to restrict access.

A. Groups

Access Control Rules are applied based onroles, not groups. While roles can be assigned to groups, ACLs do not directly use groups.

B. CRUD

CRUD (Create, Read, Update, Delete) isnot a method of setting permissionsbut rather theactionsthat ACLs control.
