Pre-Invoice Amount for Report from Delivery document

I need to create a document with Pre-Invoice Amount from Delivery Document.  I don't want to Invoice, but only get the amount.  I can see this amount from VA01 after clicking 'Billing Document Overview' or from VF04 'Collective Billing Doc./online'. 

From VF04 Not the 'Collective billing document, which saves.  I don't want to save or invoice.

Thanks,
