Releasing a shipment order is done when all necessary data is entered and when it's ready to be connected to a shipment.
The shipment order may only be released in status Planned. It is not possible to revert from In Progress to Released.
The status of the shipment order is changed from Planned to Released. If a shipment order line with no part exists, then upon releasing the shipment order is changed from Planned to In Progress.
The order is now possible to connect to a shipment. This can be done automatically if the Shipment Creation is set to At Order Release.
The order may not be deleted anymore. It has to be cancelled if the progress is to be stopped.
