There are a couple of possibilities here:


- Go in to the Full Details of the Sales Order and check to see whether Single Delivery Order has been ticked by mistake.


- Look in the Company Location to see whether Despatch Full Orders Only has been ticked.


In either case you can over-ride the setting if you need to get goods despatched
