Received Customer Payment - But Some Orders on BackOrder - How can I partially ship and record unearned revenue?

Dear Zoho Community-

  1. I received payment from customers, but part of the invoice is on backorder.
  2. I still ship the items I can.
  3. I try to use the backorder function in Zoho directly in the Sales Order but then I can't create a package because the Sales Order is on hold
  4. How can I make the partial shipment, but still record the invoice as paid with the money received on the backordered item going to Unearned Revenue?
