Impacted Service Related list : how to hide NON operational CI/service

[Servicenow lear]

Hello ALl,

We are implementing Service Map.

We are seeing a behavior on impacted services related list : where in we are seeing non operational CI/services in the list.  How can we only allow related items that are operational ?

you can do it in 2 ways :

update list layout 

or BR

1. Navigate to System UI → Related list conditions.
2. Click New.
3. Set:
   • Table: Incident (or the task table where you want this behavior)
   • Related list: Impacted Services/CIs (this is the M2M table task_ci)
   • View: (leave blank for all views, unless you want it view‑specific)
4. In Condition, add:
   • Configuration item → Operational status is Operational
     (field path: Configuration item.Operational status)
5. Save.

 Before‑query Business Rule 

If you truly want to always suppress non‑operational items from that related list’s underlying table, you can add a Before → Query BR. This affects all queries (so use conditions!).

Table: task_ci
When: Before
