Comment 30 for bug 1155679

@Sebastien
If Mr. Dupont starts working for company B, you have to create a Mr. Dupont for Company B (instead of moving mr. dupont from company a to company b) like you would do for any subsidiary. So, you have Mr. Dupont working for company A (<email address hidden>, phone: companya+dupontsuffix, ...) that you can desactivate if you want and mr. dupont working for company B who are two different persons.

But, if you want to manage one persone working for several companies, you can install base_contact. It allows to manage data related to persons (Mr. Dupont) and not only to their role within their company. With the new base_contact module (7.0-base-contact-xal on runbot) you can handle it without problems. It will work perfectly: 1 person Mr. Dupont, 2 contacts (Mr. Dupont Company A & Mr. Dupont Company B)

No, overwriting the create and write, so that all contacts have the right data in the DB.
