Sometimes, when attempting to enter a new SO, we get the "ending" questions, starting with "this SO has no lines or freight...".
 
We are using the latest T7 screen, set to Classic Look and no Opening List.
 
It seems to happen when the SO-A screen has been sitting there for a while with no activity. The SO # field is active, and when we press Enter to get to the Customer ID field we get the questions you'd normally get when you Save. It takes the next number and creates a SO with no data. We HAVE been able to "edit" that SO and pick a customer and enter lines, but it does mean that the numbers are out of order from the actual receipt time.
