How do I restrict users to only see records assigned to Assignment groups they are members of?

[Malin1]

Hi,

how do I restrict users to only see records (incidents, xxTasks, problems, changes ) assigned to Assignment groups they are members of and caller to? I have created a specific role since the restriction should not apply to users with the role itil. 

Why we would like to have this restriction is that we have supportgroups out in the business that should not be able to see and work with all incidents, SCTasks, problems and so on. 

I am thinking maybe BR or ACL?

New to Servicenow and developing so any help would be highly appreciated, thanks

Hi @Community Alums,

I would like a similar thing but make my BR more dynamic. I want all security incidents to be restricted to all users except those assigned to the assignment group of the security incident.

Thanks in advance for your help.
