Business Object BUS2078 Quality Notification

Dear Friends,

from Qulity Notification I can call the QM-Order.

But in the Data model the QM-Order is not included.

I have the suspicion that the QM-Orders are not part of the Data model BUS2078.

I think it belongs to a different BO.

Am I right?

Could you give me a short explanation.

Thanks in advance.

Joerg
