Detailed Explanation of OE COMPLETE field values

In the OE Finder window, there is a column labeled "Order Completed". Based on the Sage 300 v2014 AOM, an OE can have 5 COMPLETE field values:

1 = Incomplete/Not Included
2 = Incomplete/Included
3 = Complete/Not Included
4 = Complete/Included
5 = Complete/Day End

Some of them are fuzzy to me to explain. Can someone elaborate in layman's term what each means?

Let me start with the easiest "5=Complete/Day End" --> OE is "posted"/saved; Item quantities in IC are updated accordingly; IC Day End Processing has been run and includes this transaction; a GL Batch includes this transaction and has been posted to GL affecting Inventory costs, Customer Balance, etc....

Thanks in advance for your help.
