how can we relate 2 application services using relationships so that they both reflect on the impacted sevices on CHG or INC?

Ex: we have a legal hold-prod app that uses the MID servers which are connected to ServiceNow-prod application service.

Now if a CHG is created on " legal hold-prod" , the impacted services should reflect "ServiceNow-Prod " app as well. How do I acheive this?

Hi there @chaithra10 

If your goal is to see both services in Impact Analysis for CHGs/INCs, I'd recommend creating a service-to-service dependency between the two Application Services (e.g., Legal Hold-Prod Depends on ServiceNow-Prod). Then make sure the relationship type is included in your impact analysis traversal rules.

If you're already modeling the dependency through MID Servers, check whether Impact Analysis is configured to traverse those infrastructure relationships. In many cases, a direct Application Service dependency is the easyy approach and gives the expected results.

You can create relationships between them as follows:

Service Instance → Depends on / Sends data to → Service Instance (CSDM 5.0)

However, this relationship will not be reflected in the Impacted Services section because impacted services are populated through the CI-to-Service Association table.

The svc_ci_assoc mapping should be automated and not maintained manually. Operators, on the other hand, can open the service instance and view the relationships directly.

I would recommend exploring the concept of a Parent Application Service. Also, review how the svc_ci_assoc table works and how associations are populated within it.
