Comment 1 for bug 1407782

Hi team add explication:

it is necessary that the total invoice should only be made upon delivery of the product as our customer takes around 30-60 days to deliver the product,

because this should be done only a partial invoice total product price because they can not collect a bill from a product that has not been delivered

for example sell a product at $ 2500 USD but the product takes to be delivered 50 days before the delivery he can collect a partial invoice for $ 500 and another $ 2000 USD when the delivery this made then you can make the total invoice for the remaining

This lock is to prevent the invoice total be made for the price of the product

I hope this explanation may serve to clarify the situation
