The Sales Order Status is listed with the header data. It can also be viewed in the subheader, in context with all the other statuses.
Sales Order statuses
There are 6 statuses:
New - Has not yet been sent to picking. Therefore, items can be added, edited, and/or deleted.
In Progress - Sent to picking. View only.
Completed - Order has been shipped and invoiced.
Partially Filled - Order has been partially filled, shipped, and invoiced. This may occur when you have a stockout of one of the line items. If a Sales Order is filled with multiple picks, then you'll see the latest Pick reference number in the head and all other pick records in the Pick History. To view the Pick History, go to Header buttons, More/Pick History
