In ServiceNow, data policies enforce rules to ensure data consistency and integrity across the platform. They can be applied at both the server-side and client-side, even outside the standard UI (such as data imports and APIs).
How Data Policies Apply to This Scenario:
Incident numbers should be read-only on all lists and forms, for all users.
Data policies can enforce field read-only rules globally.
The Incident number (Number field) is typically auto-generated and should not be editable by users. A data policy can ensure it remains read-only across all interfaces.
Short Description field should be mandatory, on all records, across all applications, on insert.
Data policies can make a field mandatory across the system, not just on specific forms.
Unlike UI policies (which work only in forms), a data policy ensures this rule applies even during imports and API updates.
Why Other Answers Are Incorrect:
B . Dictionary Design Policy - No such policy exists in ServiceNow.
C . Data Quality Policy - This is not a defined policy type in ServiceNow.
D . Field Criteria Policy - Not a recognized policy type in ServiceNow.
