Here are the steps you need to take to process these requests so you can see them in Electronic Delivery:
The items should show up now in your Electronic Delivery Window.
Someone may have processed electronic delivery. When they do this, the items move to "In Electronic Delivery Processing." If they close the ILLiad Client, then they will stay at that status. If the same person goes back to Electronic Delivery, they will see the items in the Review or Print box to be processed. Because they are at the status of "In Electronic Delivery Processing," you cannot process them through Odyssey. You would need to route them to "Awaiting Odyssey Processing." Then you can process Electronic Delivery, and then they should show up, and you can deliver them to your patrons.
Sometimes, the Process Files button is grayed out when you process files.
