Why does preview invoice generate a blank invoice?

Question

Why do I get a blank invoice preview when I select Actions > Preview Invoice from the customer order screen? Why do I have invoices without SKUs in my invoice list?

Answer

If a blank invoice is generated after selecting Actions > Preview Invoice from the customer order screen, the most likely cause is that the customer order has not been picked. Return to the customer order screen and ensure all lines are picked. 

1. Select the Column visibility button and add Qty Picked and Difference to the visible columns.
2. Select Scan & Pick to pick the order.
