Kendra, I followed the instructions and the SKU column does appear now on my purchase orders and apparently my invoices as well. However it does not populate that column when I email or print the purchase order. That is the part that is the most frustrating and seems to us as users would be a very easy update for QBO. 

This function and the ability to partially receive purchase orders did not come over when we changed to QB Online but were both available options in QB Desktop. HELP US OUT !!!!
