B2B and B2C contact

Summary

Same contact as B2B contact and B2C customer

Content

I have come across a scenario where, a contact can be a B2C customer  as well as B2B Account's contact.   I would like to know how can this be handled.

What I understand?

Fusion Data model allows multiple usage assignment for a party.  I confirmed this by creating a contact of type 'Customer' and queried the HZ_PARTY_USG_ASSIGNMENTS table it has two record automatically  one with usage code Sales_Account and other with Contact.  This means for the same party record there are two usages.
