A person should be shown with a many to many field. A person as himself and in relation to an or multiple companies.
In the most international companies I worked for (especially pharma and food companies), they had employees responsible for different companies. So the very same person purchased for different companies at the same time.
For example:
John Doe is employed as purchasing agent at Supergreedy Holding Inc., which owns 6 different companies he is now purchasing for at the same time even sometimes at the same suppliers.
Supergreedy Pharma Inc.
Lessgreedy Pharma Inc.
Stillgreedy Pharma Inc.
etc.
In Odoo I have to put the very same person 7 times with all his contact data into. And if he wants to purchase one item for himself, I have to keep 8 contact files up to date. That doesn't make sense and it is quite a mess.
So: Is there any add-on out there, which does, what I need?
