CBO design and relationship between CBO root and CBO nodes question

[leocheunghbs]

Dear all,

I have to translate my database model to SAP CBO, let say Invoice table, each invoice contain product_id, associate to Product table's product_id

Is it the correct way that I create 2 different CBO, one for invoices, another for products?

So the products CBO can be reuse by other CBO, e.g. Product_Category

Or I must create a CBO with root node - Invoices, and child node - Products?

I have read this tutorial - https://blogs.sap.com/2017/10/26/sap-s4hana-cloud-key-user-extensibility-create-custom-business-obje...

The schema of the root and sub CBO:

Just wonder, why the tutorial doesn't have any key to assoicate each node.

Many thanks if someone can give me some advice.
