This tools seems to show me all the Voucher fields for every Receive Voucher for every PO in the system.  I also noticed that it had an EDIT tool to edit the selected voucher. 

I happend to note other functions I am not too familiar with (Assign, unassign, update invoices) but did not want to start playing if it caused a problem.

Where can I find documentation on this tool?  I think that our finance group would LOVE this as it gives a clear view of all fields and allows easy editing of Vouchers, however I am not sure if we should be using it.
