Start position
There are four methods of selecting the start of the itinerary:
Use selected item
This option will be active if a single item is selected prior to starting the Itinerary command.

Check the tickbox for any location(s) to be added to the itinerary and click OK. These will then be added to the Select route positions by clicking on the map dialog Location list
Note: This list is based on the entire overlay so it should not be generated on large database tables.
Added selected locations will only be active if more than one item was selected when the Itinerary command was started. This will add all of the selected items on the locations overlay to the itinerary. The Select route positions by clicking on the map dialog will be loaded with these locations, i.e.:
Click Next.
The Calculate itinerary dialog will be displayed in one of two forms:

If you wish to use Calculate optimum route with less specified positions you can click the back arrow button (top left) to return to the Select route positions by clicking on the map dialog and remove one (or more) of the route positions from the list. Again click Next, the Calculate itinerary dialog will now be displayed with the Calculate optimum route details and Calculate button shown.
If an error message is shown, similar to:
This indicates that the links in the topological network have not been set.
