Invoice Date  (aka Vendor Invoice Date)

The Invoice Date is an optional user enterable date to be associated with the Financial Document.  You can search for Vendor Invoices based on this date.  

While you can enter any date you desire, a typical usage may be to record an identifying date from the Vendor Invoice.
