Specifies the general information that relate to the vendor invoice that will be registered as a preliminary posting when the inward registration is posted.
It is not important if the vendor invoice is one of several partial invoices that are linked to a single purchase order.
It also is not important if you accidentally create inward registrations for a vendor invoice number several times, as the inward registration will automatically be made once for the purchase order/invoice.
The actual invoice values are recorded in the Inward Reg. Line table.
