When an invoice, currently in the review process and displaying in the Approve Invoices, Pending status, is modified, the invoice is systematically recalled. It will display in the Recalled status pane. When the invoice is rerouted, for any of the assigned Reviewer(s) who have already approved the pre-modified version of the invoice, this revised version of the invoice will display in their Approve Invoices, Reapprove status as well as their Pending status. For assigned Reviewer(s) who had not yet reviewed this invoice, this invoice will be visible in their Pending status as expected.
Note: 
, 
and 
buttons are enabled in the toolbar for an invoice in the Reapprove status.
