How Assigned to user was able to change the assigned to field, As of now it is read only

Hello,

For a GBS Case, the assigned to user was able to change the assigned to field.
As of now the field is read only now the users are not able to do so.

So what could be the reason the users were able to change.
And kindly refer the attached screenshot what is that human like icon next to the assigned to field.

Hi @ashutoshwor,

Hard to say without seeing the table configurations, but here are two possibilities to check:

• The read-only attribute is only applied from the client-side
  • UI policy, client script, etc. 
  • And it was bypassed by editing through a list view,
  • Try impersonating the user who made the change to confirm,
  • If so, enforce it via Data Policy or ACL instead.
• Some automation like an UI Action is auto-populating the field.

Without access to the configs it's impossible to say for sure but you can start with those two and let me know what you founnd
