Hi @dvass0107 ,

As per my understanding, Below solution and approach will help you.

1. Can we “use” the same attributes? 

Not directly in the sense of them being literally the same field.
* Business Application (cmdb_ci_business_app) and Application Service (cmdb_ci_service_discovered) are two separate tables → each has its own set of fields.
* If you want the same kind of data (e.g., Business Owner, Service Owner, Criticality, etc.) to appear on both:
* You add equivalent fields to Application Service.
* They won’t automatically be linked or synchronized just by default.

2. How to keep them in sync or reused? There are several ServiceNow-standard ways, depending on what you want

Option A: Inherit via relationship
* Establish a relationship:
* e.g., Application Service → depends on → Business Application.
* Then, when you need the Business Owner on the Application Service:
* Reference the value from the related Business Application in UI (dot-walk).

* Example:
* In a form or list: business_application.business_owner
Pros: no duplication. Cons: only works if you keep the relationship consistent.

Option B: Copy fields during creation
* When you create an Application Service, copy values from its related Business Application (using a Business Rule, Flow Designer, or Script).
* Keeps them as independent fields, but initialized.
Pros: simple, quick. Cons: needs logic to keep updated if source changes.

Option C: Shared dictionary extension (advanced)
* Create a parent table with shared attributes, extend both tables from it.
* Rarely done in standard CSDM, because CSDM intentionally keeps these tables separate.

3. Which is recommended in CSDM?
* The CSDM model: keep Business Application in Design domain; Application Service in Technical domain.
* Use a relationship (Depends on::Used by) between them.
* Use dot-walking to reference common attributes (like Owned by, Managed by, etc.).
* Only create custom fields directly on Application Service if you really need different / runtime-specific data.
