Just got off the phone with QB support for QB Enterprise. This is still not resolved and still an issue. Yes, if you leave the "Description on Sales Transactions" section blank it will transfer the description on your PO. However, I don't always outsource custom items and don't create PO's for sales we produce in house so I need the basic "Description on Sales Transactions" to be filled out. 

They do give you the option to transfer the item description under mileage so the coding is written for this to be applied to Items as well. Such a powerful program but they miss so many basic things that creates more work.
