How to add CI to an existing application map using Flow Designer?

[Yuuki Tamori]

Currently we have a flow Order Management that creates a new CI when an order task is completed and relates that CI to an existing service map in our flow designer.
In the process, we are thinking of creating a script action to update the application service map based on the following two articles.

If I want to add a new CI to the map while leaving the existing application service map in its current state, what kind of script should I create?(See attached file for an image of the addition to the service map)

I think you should have a try with BusinessServiceManager API.

Unify service management by converting manually-created services to application services, populating application services, and adding/removing CIs and connections.

Use BusinessServiceManager methods in global server scripts. You must have the Application Service administrator [app_service_admin] role.
