[ADD] sale_order_partial_invoice

This module allows invoicing a partial quantity of Sale Order lines

From the module description:

    With a sale order in 'manual' invoicing policy, when the user selects to
    invoice some SO lines, a new wizard is display in which it is possible to
    select how much of the different lines is to be invoiced. The amounts
    invoiced and the amounts delivered are also displayed. When generating an
    invoice for the whole sale order, the partial invoices are taken into
    account and only the amounts not already invoiced are part of the new
    invoice

[Alexandre Fayolle - camptocamp (alexandre-fayolle-c2c)]

To use it / test it:

* create a SO with several lines (products and services can be used),
with "manual" (On Demand) invoicing policy
* deliver (partially or completely)
* click "Create Invoice" and select "Invoice some order lines"

A wizard is displayed instead of the List view of sale order line, and
it is possible in that wizard to change the quantity which will appear
in the invoice. The already invoiced and delivered quantities are also
displayed (for services the delivered quantity is equal to the invoiced
quantity).

If a partial invoice was generated, generating a new invoice for the
whole Sale Order takes the partial invoice into account.

Just committed small neat pick.

LGTM, but it would be nice if Alexandre can just redo a run of test with last fixes.

Hi Alexandre,

This contrib, really rocks ! A question:

 * When displaying the lines and quantities to invoice (with Line;Sold;Ivoiced;Shipped;To invoice ), I didn't understand why fields are not in read-only except "To invoice" one ? Any reason not to let the user change other field ?

A part from that, it looked perfect to me, it was just like this that I expected this to work, thanks.

Regards,

Joël

You are right, I'll make the required changes.

+ * Adding qty_invoiced field on SO lines, computed based on invoice lines
+   linked to it that has the same product. So this way, advance invoice will
+   still work !
+
+ * Adding qty_delivered field in SO Lines, computed from move lines linked to
+   it. For services, the quantity delivered is a problem, the MRP will
+   automatically run the procurement linked to this line and pass it to done. I
+   suggest that in that case, delivered qty = invoiced_qty as the procurement
+   is for the whole qty, it'll be a good alternative to follow what has been
+   done and not.
+
+ * Add in the "Order Line to invoice" view those fields
+
+ * Change the behavior of the "invoiced" field of the SO line to be true when
+   all is invoiced
+
+ * Adapt the "_make_invoice" method in SO to deal with qty_invoiced
+
+ * Adapt the sale_line_invoice.py wizard to deal with qty_invoiced, asking the
+   user how much he want to invoice.
+
+By having the delivered quantity, we can imagine in the future to provide an
+invoicing "based on delivery" that will look at those values instead of looking
+in picking.
