If you need to reject one or more orders you can select the orders from the dashboard, right click, and choose 'Reject'. This will change the orders back to a status of 'Rejecting' and they will be wet to rejected on the next run. To set them to rejected straight away then click on the process button.
Note that orders you may not be filling can be identified on the screen as they do not usually have invoice numbers.
