Hello.

When you create a contact and assign it an RFC or VAT and save it so that the contact is created, it is saved with the information that you indicated in the RFC, when you create a contact for the same contact that you just created and save it It is automatically saved with the same RFC that was saved in the parent contact (or the company), what function does this do? How can I prevent the child contact from being saved with the same RFC as the parent contact?
