How to make incidents hidden by a specific assignment group

[Joshua Comeau]

Wanting to add new assignment group IT Security Incidents:

Would like this group to have its incidents only visible to members of the group.

EX: Any incidents assigned to this group only make them visible.

Hi Joshua,

You can achieve this either by Query BR or via ACLs of type read.

Did you try something from above? If so, are you stuck somewhere?

I'd recommend using Data Filtration features - Exploring Data filtration (servicenow.com)

...it works similar to the way that User Criteria does for Catalog Items and Knowledge Bases or articles. Basically you can set up a rule where the data is filtered out ("Not available for" in User Criteria terms) for users who are not in the assignment group, if/when an incident is assigned to a specific group.

I believe this feature was rolled-out in San Diego and before that time, you could only achieve this via before-query BR and/or Access Control records...and in my experience this can get difficult to maintain, though it can still work (depending on your business requirements).

I created this ACL:

Data filtered:

did not work everyone can still see the incident 
can you provide screenshots of a working configuration

Just to be clear, the Data Filtration features that I am referring to are NOT Access Control records. They are used INSTEAD of the BR or ACL solution and IMO are better as they are easier to configure and maintain.
