Situaation example:

Customer # 0987 application 001 date 2017/01/07

Product A 15u. (Done)

Product B 20u (waiting)

The customer receives an invoice for the goods delivered, waiting for availability of the rest of the material

The same Customer # 0987 request 002 date 2017/01/12

Product C 15u. (Waiting)

Date 2017/01/13I receive the products B and C and to the client Client # 0987 a single delivery is made with the current order and the remainder pending

The customer must receive a single invoice of this second delivery

What do you advise me?

I have thought about canceling the rest of the order 001 and adding it to the order 002, but sometimes there are quite a lot of order lines.

It can also happen that the customer makes different orders and they are invoiced in a single invoice. (Collect different orders on a single invoice)

I currently use Odoo v10

Thanks in advance
