As per the SID model, only Atomic POs can have PS:

But I have seen models, where they have a relation between the Composite/Bundle PO and PS (in case they need to charge the Composite PO independently from the Atomic POs).

Hi,
If we have productOffering that has isBundle=true, can this productOffering have productSpecification or it must not have productSpecification?
It is not clear to me if productSpecification is Optional in this case, or forbidden?
If we take a look at document TMF620B_Product_Catalog_API_Conformance_Profile_v4.1.0, there we have this stated:

Thanx,
