All Available Invoice Numbers have been Allocated or Used V8
Overview
User is receiving a message that "All available invoice numbers have been allocated or used" on the handheld when trying to service a stop.
Cause
Not enough invoice numbers allocated on the Route Master setup.
Resolution
On the desktop, go to Lists > Routes > Route Master.
Open the tab labeled "Invoices".
Modify and change the field for "Off-route Inv. Qty" - this is the amount of invoices allocated off-route for this stop, the driver will not be able to service more than this amount of stops off-route.
If this is the first stop the driver is servicing, the driver can go ahead and re-download their route for the day and start the process over. If the driver is in a middle of a route, they will have to do paper tickets until the next time they are able to download a new route.

More Information
Review the setup for all of your routes in the Route Master List to ensure the correct amount of off-route invoices is set. You also do not want to set this number too high, as it will use up those invoice numbers for that route and day even if customers are not serviced.
