Making a field mandatory after it is assigned to a particular team

[Rachael12]

I need to make fields mandatory after the ticket is assigned to a particular team. Basically the assigned to person needs to fill them.
How do I do it, also I want that the mandatory(*) symbol is visible on the fields.

I have tried UI policy and Data policy but does not do the job.
Condition applied is :

Assignment Group is X and Assigned is empty.

Hi there @Rachael12 

You can do this via UI policy

• Table: your ticket table (e.g., Incident)
• Condition: Assignment Group = the groupp 
• On load:  check this

UI Policy Actions:

For each field:

• Mandatory = true
• Visible = true (if needed)

This should work.
