Two cases :
Case 1:
A parent company contact has several IBANs (so is holder of several mandates) : IBAN1, IBAN2, IBAN3....
This company has several children (where the products are located): child 1, child 2... They are also contacts
When we send a bill to the child 1, the child 1 address is taken as delivery address but the bill is invoiced to the parent company (with the mention of the child 1) and the beneficiary account is IBAN1.
How manage the fact that the parent company contact has several IBANs and not only one?
Case 2:
A parent company contact with several children (who are also contacts) , each of these children has its own IBANs. But the invoicing bill is for the parent company.
How can we fix that situation due to the fact that Odoo will take the company linked to the invoicing address for the registration of the payment?
