Note
Field names must be unique for a class. If you enter a name that
already exists, a message displays.
Confidences
For each field, a confidence value called the Locator Result Threshold can be used to
govern the acceptance of results from a locator.
A locator typically returns several items that match the locator definitions. These are
called alternatives. Each alternative is evaluated and assigned a confidence by the
locator. The locator copies the best alternative to the field among all the items that
have reached this minimum threshold.
The Validation Thresholds are used to determine whether or not a valid state should be
assigned to the field. The field is given an invalid state if either the confidence is
lower than the minimum confidence threshold or if the distance to the next
alternative is less than the minimum distance.

Two confidence thresholds can be set for the field:
Locator Result Threshold
A locator’s best alternative is only assigned to a field if its confidence is equal to or
higher than this value. The field will be empty and its state is set to ‘invalid.’
