You are prompted with the below message, which if you leave the line in the top section it will in turn update the system so that the quantity can be put into stock and then effectively allocated.
If you click the 'Move Down' key this will then leave the item unchanged so you can then purchase the item and it places the item into your Requirements list to purchase.
When you have moved the item up, down or left it as it is, you will then need to click the 'Update Stock' so that it registers that you want to purchase or allocate new stock.
