I usually copy a Sales order and then adjust the quantity to one and then change the value to “0”. When I select issue, a message says ‘no shipments exist for this order’

In VISCO, something different happens when you copy a sales order. In SO Assign at the bottom left (down by the assign button) there is a Future Order Checkbox. When you copy a sales order this box gets automatically checked -the system assumes you’re entering an order but not for right now. If this checkbox is checked, NO shipments/releases are automatically created. To avoid this, uncheck the box before you click Assign. If you have assigned and the box was checked, go to SO Preparation, the Lines Tab, click on the “Auto generate shipments” link and enter the ETD and ETA this will create the shipments/releases you need
