Error: Using dynamic segmentation commands to display event information for defined layers produces 'Attribute column not found'

Error Message

Using dynamic segmentation commands to display event information for defined layers produces the error Attribute column not found.

Commands for which this error can occur includes EVENTMARKERS LAYER, EVENTPOINTTEXT LAYER, EVENTLINES LAYER and EVENTLINETEXT LAYER.

Cause

The {route_key_item} and {event_key_item} must be identical in the EVENTSOURCE which is established for the layer.

Solution or Workaround

  1. Use the ALTER command in tables to modify the route_key item or event_key item so that they are named the same. Another option is to add a matching route_key or event_key item to the appropriate table and populate it with the values from the original item.
  2. Create a new EVENTSOURCE using the identical route_key and event_key items.
