When going into Assess Finance Charges page in the past we have been able to apply a finance charge to a client, and then NS creates the new invoice which in turn we can go back into and edit. For some reason now you can not edit any finance charge invoices by line items without getting an error. For example if we go into the invoice that the finance charge page assed and change the line item from say $25.00 to $50.00 maybe because there were two late invoices and save it, we get an "unexpected error has occured" message.
