Only some items have been received on the purchase order...

...but when I go to receive the remainder of the items on the PO from a subsequent invoice, the PO has disappeared out of the pop-up window, even though it's not technically closed.

How do I make sure the PO stays open so I can continue to receive all the items?

I have found that items that are not invoiced on an initial invoice need to have the quantity changed to zero when you enter the first invoice and then those items are still available when you get subsequent invoices.
Hope that helps!
