Hi,

Hard to answer without more specific information, but for what you have asked for I would say this covers it: https://community.servicenow.com/community?id=community_question&sys_id=64d51c06dbbda7002e8c2183ca96...

Hi,

They all have different purposes.

ACL - Purpose of this is to ensure what data users can access and how they can access it

Client Script - This is for Client side (or browser side) validation. Client side validation includes, making a field mandatory, read-only, hidden etc. This will get applied only at the browser.

UI Policy - This is similar to Client Script, except that not need to write a script

Business Rule. This script runs at the server side when a form Insert, Update etc. This can do some action that can be achieved only by running from Server.

Field State (Mandatory,Visible, Read only) is generally applied in the following order of preference, where one is the top preference:

1. ACL (Visible/Disabled)
2. Dictionary Entry (Mandatory/Disabled)
3. UI Policy (Mandatory/Visible/Disabled)
4. Data Policy as UI   (Mandatory/Disabled)
5. Client Script (Mandatory/Visible/Disabled)

 Examples:

If the user does not have write access to a field (ACL), a UI Policy to make it editable will do nothing.

If a field is set to disabled on a Dictionary Entry, a UI Policy to make it mandatory or editable disabled will do nothing.

If a field is made read only by a Client Script, a UI Policy to make it editable will take preference.

3,4 or 5 may be variable based on order.

Client side code- Client-based code that executes in the browser, using Ajax or running as Javascript, always executes before the form submission to the server.

This includes Client scripts and UI Policies.

• First onLoad Client scripts, after that the first UI Policies kick in.
• After that, the Client scripts and UI Policies that work onChange.
• After that, the Client scripts that work onSubmit.

Server Side Code-

1. Before business rules:
2. Before engines.
3. Before business rules:
4. The data base operation (insert, update, delete).
5. After business rules:
6. After engines.
7. Email notifications.
8. After business rules.
