Automatically Shipped changes the Status of an Order to Shipped and sets the Orders Shipped checkbox for an order when a shipment is processed using the Shipping Connect Add-On which connects UPS, FedEx, or another system to Big Business.
This setting requires a restart of Big Business Server to take effect. Go to the Controls toolbar to MRP Settings and check the box for Automatically Shipped. Then, restart your Big Business Software to have this take effect.
