Field Properties
You can use the Validation Thresholds area in the field properties dialog box to
define the validation thresholds for each field. The thresholds are used to determine
whether a field is valid or invalid.
Another validation property determines whether a field requires manual
confirmation. Fields for which the “Require manual field confirmation” option is
checked must be validated manually in Ascent Xtrata Pro Validation, even if the
field’s status is valid. This option is useful for those cases where the contents of a
field must be absolutely accurate and there is no margin for error.

Field Formatter
Field formatters are used to force the contents of extracted fields to a predefined
format. Each formatter type has its own Properties dialog box.
For extraction fields that will be used for validation, it is recommended that you use
field formatters. For example, amount formats may contain both periods and
commas (1,500.00). To use such an OCR result for arithmetic validations, the results
must be reformatted to numeric values.
Another aspect of using field formatters for validation is that the formatters fill
special field properties (DoubleValue, DateValue, and DoubleFormatted) with the
reformatted field value. Especially for script validation, the fields are very useful, as
the user does not have to worry about reformatting the field’s text property.
