Problem
A vehicle is appearing on the exceptions report stating 'Outstanding Supplementary Invoices'.
Solution
The reason that supplementary invoices appear on the close-down exception report for vehicles, is because the user has gone into the customer order, and clicked onto either Invoice 2, 3 or 4. In turn this activates this invoice (and will then show on the exception report).
The easiest way to get rid of a blank unwanted supplementary invoice, is to go into the customer order, and go onto that specific invoice.
Once here, physically delete the "0.00" values that are active, and save the customer order. The "0.00" values will appear back in the boxes, but do not worry about this.
Once this is done, check the exception report again. You will find that this vehicle is no longer on the report.
