Once an invoice has been closed and moved to history, voided, or paid it is no longer possible to change the information on that invoice. With this enhancement it is possible to review the invoice and see what the distribution was. Nothing can be changed on these invoices, only viewed. The initial review is in the current file only. Once maintenance is completed in the current file it is possible to review the history invoices as well. When the invoice number is left blank the choices will be displayed. If history invoices are selected at this time, only history invoices will be provided for selection. When finished, change number will provide access to the current file again, or to return to history, select history again.
