Fabien... For sure we will do that and give you feedback.
But... Even if I would like to be mistaken, this is my point...

We DO need an ERP, ok? An ERP main object always is Legal Entity.
Everything in an ERP is related to Legal Entity, begining from Purchases,
pickins, invoices, accounting, and... even Claims or Opportunities are
related to a Partner/Company whatever you want to name it.
You only need contacts or addresses for communications, nothing more and
even, if you try setting a contact somewhere, this contact can change for
several reasons inside a Company as I told before (Hired, hollidays, fired,
died... ). Contact is not UNIQUE inside a company even a single contact
could be related to different companies. Contacts can be changed one with
other but legal entity never change. It's always the same. It's UNIQUE
always even if you can set different hierarchies between them. So... when
modeling an IT system if focus is not correct, everything will go wrong.

On the other side, what you did is not another version but another ERP with
a different focus different granularity, so on this case,  i think it will
be quite difficult trying to cover all possible impacts and hidden
consecuences in a short time.

That's my point and I say again: I wish I'm mistaken.

Thank you again.

> Title:
>   [7.0] incorrect handling of contact/companies for invoicing and
>   related purposes
>
> Status in OpenERP Addons (modules):
>   In Progress
> Status in OpenERP Server:
>   In Progress
>
> Bug description:
>   == Problem Description ==
>
>   This issue is an attempt to formalize the various problems detected
>   with the res.partner refactoring that took place in OpenERP 7.0. Some
>   of the issues have already been discussed on bug 1151947, bug 1155679
>   and on help.openerp.com.
>
>   The main problems identified so far:
>
>   1) When a simple contact (type=contact) is selected as the reference
>   party for creating a business document (such as the customer on a
>   Sales Order), a proper invoicing partner (if any) should be selected
>   among the descendants of the "commercial party" to which the contact
>   belongs, instead of the contact itself.
>
>   2) Even when a simple contact is used as the invoicing partner for a
>   business operation (e.g. manually selected by the user as the invoice
>   address on a SO), all invoicing/accounting-related master data must be
>   taken from the relevant "commercial party" for that contact. This will
>   usually be the parent company.
>
>   3) When editing contacts/addresses, it is currently possible to view
>   and edit accounting/invoicing related data, while it should be clear
>   that this data is coming from the "related commercial party", usually
>   the parent company.
>
>   4) When searching though business documents for a company name, the
>   entries that were issued for one of the company's contacts/addresses
>   should be found as well.
>
>   5) It has been reported that in some countries it is not permitted to
>   issue invoicing documents for a contact, so the name of a relevant
>   invoicing must be used instead (Financial Department or parent
>   Company).
>
>   6) In "Analysis" reporting views, result that are grouped by partner
>   will not be automatically aggregated at company level.
>
>   == Proposed Solution==
>
>   The rationale for the proposed solution is based on the following points:
>   - We think the 7.0 partner model is appropriate and should not be
> considered the cause for these functional/usability problems
>   - We think the solution should be mostly handled by the res.partner
> model itself, so that it fixes most modules automatically.
>   - We think that in many cases, using a contact/address is the right
> level of granularity, and any reporting based on that is fundamentally
> correct. Invoicing/Accounting is specific for the reasons mentioned above,
> and automatically selecting the proper entity to use should make reporting
> provide the expected result.
>
>   Based on this, we propose the following solution. Parts A & B are
>   meant to solve the issue of using the right invoicing/accounting data
>   at all times (issues 2 & 3 mainly), while parts C, D & E  are meant to
>   improve the selection of invoicing entities and the related reporting
>   (issues 1, 4, 5 & 6):
>
>   A) Let the "commercial party" for a partner be the person or company
>   that is used as reference for all invoicing/accounting matters. The
>   "commercial party" is computed as: the first parent that is marked as
>   a company (is_company is checked) or is the root of the hierarchy if
>   there is no company. It can be the partner itself if it's a company or
>   if it has no parent.
>
>   B) The relevant invoicing/accounting data will only be editable on an
> "commercial party", and all contacts/addresses that are descendants of an
> "commercial party" will inherit those settings. This will be done as
> follows:
>   - when a partner is not an commercial party, the form view will be
> modified: the Accounting tab and the Invoicing section of the
> Sales&Purchases tab will be replaced by a note that says something like
> "Invoicing settings are controlled on <link to commercial party>".
>   - when writing() on a partner that is an commercial party, all the
> values of invoicing/accounting-related fields will be automatically copied
> to all descendants that are not commercial party themselves (e.g.
> pricelist, G/L accounts, payment terms, etc.). The list of fields to copy
> will be returned by a method on res.partner that can be overridden in other
> modules.
>   - when changing the parent of a partner causes a change of "commercial
> party", the same fields will be copied
>
>   C) When a contact/address is selected as the reference for a business
> document (SO/PO), the system should automatically select appropriate
> invoicing and delivery parties from the relevant "commercial party".  This
> is the responsibility of the res.partner.address_get() method (legacy name
> for backwards-compatibility), and it must be adapted for the new model.
>   The new algorithm should search in the whole hierarchy of the partner,
> stopping at the parent "commercial party", as defined in A. This will be
> used automatically by the on_change triggers on SO/PO/etc, and should
> ensure that the proper invoicing and delivery partners are always selected.
>
>   D) The res.partner.address_get() method considers the partner type
> "default" as a wildcard, so any partner with type "default" is seen as a
> match for any requested type. This is correct but unfortunately "default"
> is the default value, which would stop the lookup described in C at the

> so that unless otherwise specified a simple contact cannot be used as
