We are looking for a solution for this questions in Odoo 8:

1. We create a proposal for a client . We have a partner in this client. The partner should be the addressee and not the company because we want to send the proposal as PDF to the partners mail addresses that is different to the clients mail address.

2. We create an invoice for a client. The invoice should be send to the partner with address type invoice.

3. If we create the invoice the postal address in the invoice should be the postal address of the partner and not the company.
   

We've tried this with different settings. All the time the invoice will eb send to the clients mail address. What are best settings?

What is the function behind partner address type?
