Field "Country of Origin" vs Rule of Origin

Summary:

Field "Country of Origin" vs Rule of Origin result

Content (required):

"Country of Origin" in Item Origin record is a mandatory field to create an Item Origin. Without Item Origin, GTM cannot run Rules of Origins to determine FTA qualification. What if country of origin is not known when running the FTA qualification and system is depending on Rules of Origins to calculate the Country of Origin?

Furthermore, does the field "Country of Origin" on parent item play any role when GTM runs Rules of Origins? Otherwise why must it be mandatory?
