Hello,
When I Was Create Sale Order And Confirm at that time delivery Order state was in waiting(Waiting Another Operation) but Product On-Hand Quantity is for e.g.1000 Or Order Quantity for e.g. 200
So basically if Quantity On-hand is more than order quantity at that time delivery order state is an available.
Thanks in Advance
