🔹 What Is a UI Policy?

A UI Policy controls form behavior in the user interface (UI).

It dynamically changes how fields behave when a condition is met.

✅ What UI Policies Can Do:

• Make a field mandatory

• Make a field read-only

• Make a field visible/invisible

🔹 What Is a Data Policy?

A Data Policy enforces rules at the data level, regardless of how the record is created or updated.

It ensures data integrity.

✅ What Data Policies Can Do:

• Make a field mandatory

• Enforce read-only behavior

• Apply to:

  • Forms

  • Import sets

  • Web services (REST/SOAP)

  • Background scripts

  • Flow/API updates

🔥 Key Differences

Feature UI Policy Data Policy

Works on form only	✅ Yes	❌ No (works everywhere)
Enforces via API/import	❌ No	✅ Yes
Prevents bad data from integrations	❌ No	✅ Yes
Primarily UX control	✅ Yes	❌ No
Data integrity enforcement	❌ Limited	✅ Strong

Hi @ShivaR437725225 

UI Policy in ServiceNow is a client-side configuration tool that acts as an alternative to Client Scripts. It runs on the client side (browser) and allows you to dynamically control field behavior on a form without writing any code.

With UI Policy, you can:

• Make fields Mandatory
• Make fields Read-Only
• Make fields Visible/Hidden

You can also set conditions so that field behavior changes dynamically based on what the user enters or selects on the form.

The biggest advantage is that it's purely configuration-based, making it simpler and easier to maintain compared to Client Scripts. However, for more complex logic, Client Scripts are still the way to go.

Hope this helps! ,if yes then kindly mark helpful & Accept as Solution😊

Reasons to Prefer UI Policies over Client script:

              Declarative vs. Programmatic: UI Policies are a no-code/low-code, configuration-based approach, allowing administrators to define rules without writing JavaScript. Client Scripts, conversely, require JavaScript knowledge and are customization-based.

• Performance: UI Policies generally have less performance overhead for simple operations, contributing to faster form load times.
• Maintainability: They are easier to manage and understand for other developers or administrators, as the logic is clearly defined in the platform's user interface.
• Execution Precedence: UI Policies run after Client Scripts. If both modify the same field, the UI Policy's logic takes precedence, which can lead to unexpected behavior if best practices are not followed.
• Simplicity of Use Cases: They are ideal for straightforward use cases like:
  • Showing or hiding fields.
  • Making fields mandatory or read-only.
  • Controlling behavior based on simple conditions

Hello @ShivaR437725225 ,

Yes you are right, UI Policies are indeed client-side and a great alternative to client scripts when you just need to control field behavior dynamically—like making a field mandatory, read-only, or visible based on conditions. They’re simpler to maintain than scripts.
