Use this window to display voucher row information for the vouchers in the hold table. Since this is a query window, you cannot change any of the information; you can only study the result of performed transactions.
You can view any documents attached to a voucher by right-clicking on the window, and then clicking View Connected Document. (i.e. the image of the invoice which was based to create the voucher)
Activity descriptions are available through activity objects in the Activity Diagrams.
