Duplicate Index on any data entry screen (line item related)
Duplicate Index upon saving a change in a screen
                  
All Orders 3.X
                  This can happen due to repeated items on an order when  
                  the repeating items are placed after the first line and contiguous
                  Resolution:
 Delete one of them or amalgamate (combine into one) or place with at least a different
 item in the middle...this is a temporary solution while we come up with a final one
