Is it possible to have it that a popup or warning is triggered upon entering an item, that is out of stock, into a Sales Invoice or Sales Order?
Currently, the only warning that appears is once you have checked the "ok" box and then go to save the record.

The issue is, when a customer places an order over the phone, we will enter all their items into a sales invoice, process the credit card payment, and only then will we ok the invoice and save it. If we have not noticed the item bar status for that item before we have taken payment, it becomes a real pain.


Many thanks
