Comment 3 for bug 532728

Jay,
Please, try to imagine a company where all invoices are made from the packings.
Invoices created from the packings are wrong unless you show uos quantity, a field most company have no use seeing.
You can't make it right without deep knowledge of how UoS works, even when you don't want to use UoS.
When you don't make it right your invoices are all wrong and you lose money.
That's not just unusable - that's broken.

My view is that:
- a critical task such as updating the uos quantity should never have been trusted to the client in the first place
- unfortunately uos is updated client-side, so the only acceptable way to have correct invoices is solution 3.

I'm using solution 1 as a workaround, but it's not an elegant solution (we don't care for UoS), and solution 2 isn't either because as you said, "it may lead to company policy" and users scratching their heads.

Invoice from the packing is a basic feature, I beg you don't make it such a pain.
Lionel.
