Magento

I don’t know if the title is accurate, but here’s my situation:

Magento Community Edition 1.7.0.2, Authorize.net (authorize only) used to process orders.

Say I have an order with two items, and I only have one available to ship today. I invoice and then ship the first item, and the only thing left to charge is the subtotal of the second item: http://i.imgur.com/diJPD17.png

The first invoice goes through fine and dandy, and the pending capture is adjusted for the reduced amount (price of first item + shipping) on my card’s activity. However, when I go to invoice the second item, I have an error that says “Invoice will be created without communication with payment gateway”: http://i.imgur.com/d8YwdUX.png

What gives? Googling the error yields pretty much zero results, so it seems like I must be doing something really wrong to run into such an issue. Any ideas?

I’m really stuck on this, and could use some help. The only modification I’ve made to anything in /app/code/core/Mage/Paygate/ is in the authorizenet.php file.

I changed

This allowed me to edit the qty to invoice so I could create multiple invoices in the first place. Now, I can capture the amount of the first invoice, but I can’t do anything about any remaining items.

If this isn’t a bug, if this is just how Magento is, then I am appalled. Store owners need to be able to break up an order into multiple shipments and invoice those shipments separately. Can someone please point me in the direction of a way to do that?

I’m interested in a solution for this too. While I’m okay with doing the above, it is still a surprising default behavior from Magento. Anyone else can help?
