UI Policy Action fields field_message, value

[NS]

Hello, I noticed four interesting fields in the UI Policy Action (sys_ui_policy_action) table :

• field_message
• field_message_type
• value
• value_action
  
  

Their names suggest that a UI Policy Action can display a field message or set a field value. However, these fields do nothing in the Standard UI.

You can verify this yourself (also shown in the attached screenshots)

1. Add the fields to the UI Policy Action form.
2. Configure a message and a value.
3. Trigger the UI Policy on a standard form.
4. Observe that supported actions, such as Mandatory, work. Nothing more.

I was confused about these fields so I contacted the ServiceNow support. They confirmed that the core implementation limits this functionality to the Service Catalog context. Support also stated that the documentation would be updated in the “near future”. There wasn't much info about the fields, hence this post. 

The confusing part is that these fields exist on the standard UI Policy Action table, but the standard UI Policy documentation does not explain their purpose or mention that they only work in the Service Catalog.The confusing part is that these fields exist on the standard UI Policy Action table, but the documentation does not say that they only work in the Service Catalog.
