The Restore Supplier Invoice activity is to restore supplier invoices
that must be re-sent to a third-party accounts payable application, due to errors
during the previous transfer attempt. When you restore a supplier invoice, it
prepares the invoice to be transferred again.
There must exist at least one supplier invoice that has been confirmed with an error.
The Transfer Status field on the supplier invoice is reset and the entry in the Supplier Invoices in Transfer page is deleted.
