UI Policy action set value not working.

[ArmegaA]

I have created in a PDI a UI Policy on the incident table that has actions to set the value of some fields to true. One is true/false one is String ( ignore the misspelling) . 

 THe actions look liek this : 

 Ii is simply a value action set value and the value is true. I have no condition. I don't understand why it is not setting the value on a random incident I picked:

 

These are newly created fields just for this purpose so they are not in any other br, uip, uia etc. I thought maybe for the true false it doesnt do a converison from string to boolean and that is why it is not populating but the string field doesnt work either.  If I try to do a script in this and just say setValue it works as always.  Is this Set Value action simply not made for this kind of logic? What is it used for in that case?

What's your use case? If you don't have any conditions, it should just be a default value, right? 

When I check on the OOB UI policy form, there is no 'set value' available. There's only 'clear the field value'. I think the 'set value' is meant for catalog ui policies, where it is available OOB.

Hi @ArmegaA,

The Set value field is not meant for standard UI Policies.  Check existing OOB UI Policies where UI Policy action doesnt have that field.

You can try setting value for catalog variables.

Hello @ArmegaA ,

Based on my understanding, a UI Policy on a form is primarily used to control field visibility, mandatory, and read-only states. By default, UI Policies do not set field values.

From your screenshot, it appears that you added the field to the form by configuring the form layout. I tested the Set Value functionality, and it works for Catalog Variables, but I couldn't get it to work for a standard form field.

So, I don't think this approach will work here.

If this helps, please mark it as Helpful and Accept as Solution.

Hi @ArmegaA 

In ServiceNow, setting a UI Policy Action to True means the specific field behavior (such as Visible, Mandatory, or Read-only) will be actively applied whenever the policy's condition is met.
