Hi @KoyaJ ,
If I am not wrong you’re asking specifically about the “+ Add CI Relationship” button that shows up on a CI form (in the Related Items / Relationships tab).
As per my understanding, below things can be helpful for you.
Where the “+ Add CI Relationship” button comes from
* That (+) button is a UI Action that launches the CI Relationship Editor (a UI Page).
* The button appears on CI forms (cmdb_ci and its subclasses) in the Relationships related list.
* It is not hard-coded into the form — it’s controlled by UI Actions.
Configuration Path
1. Go to System UI → UI Actions
* Filter for Table = cmdb_ci.
* Search for UI Action with Name like “Add Relationship” or Action name = add_relationship.
* That’s the configuration for the (+) button.
2. Check the UI Page that’s launched
* The UI Action calls the CI Relationship Editor (UI Page = ci_rel_add).
* Path: System UI → UI Pages → ci_rel_add.
* This is where the actual relationship form logic is.
3. Permissions
* The button is shown only if you have roles such as itil, cmdb_read, or higher (like cmdb_admin).
* If you don’t see it, check your role or whether the UI Action is Active.
Best Practice (ServiceNow CMDB)
* Don’t customize the OOTB “Add CI Relationship” UI Action directly (upgrades may overwrite).
* If you need different behavior (e.g., custom relationship types), clone the UI Action / UI Page.
* Relationship types themselves are defined under CMDB → CI Relationship Types (cmdb_rel_type).
