I have a problem here where Odoo will not flag an order as delivered if we send fewer components from a kit, and do not create a back order.
Because of this we cannot create an invoice.

note: all kits, products and invoicing policy is to invoice on delivered components

We have a customer who has ordered 2 kits from us, each kit consists of:
20 metres of cable
2 video cameras

The customer only wishes to receive 15m of cable per kit and still happy to pay full price for the kit.
so we in Odoo deliver
30 metres of cable
4 video cameras

we don't create a back order (click 'no backorder'):

odoo generates 

The initial demand has been updated.

• [205] 2 core cable:

• Quantity : 40.0 -> 30.0

on the original sales order there is an exception:

Exception done

Original note:

Exception(s) occurred on the picking: \WH/OUT/00006. Manual actions may be needed.

Exception(s):

• 30.0 Units of [205] 2 core cable processed instead of 40.0 Units

im not sure what actions need to be taken (if any)

but the sales order shows:

quantity : 2
delivered : 1
invoiced : 0 

if i were to create an invoice, odoo only generates an invoice for 1 kit, not 2.

is there a way to "force" odoo to flag both kits as delivered?

thanks.
