available to the standard evaluator, so results from the SL_ResetRegEx
locator are set to 0% in this scenario.
ƒ SE_PONumber – This is a standard evaluator which selects a result from the
locators above. As mentioned, this evaluator works on a “first of” rather than
“best of” approach to allow for the enhanced dynamic regular expression
logic.
Field Settings
The PONumber field takes its result from the SE_PONumber evaluator mentioned
above. It is formatted using the DefaultPONumberFormatter, which removes special
characters. The field is set, by default, to require a moderate confidence to be valid,
and its default setting is 60%. The “min. confidence to set reread result” is set
dynamically based on the field OCR Confidence settings taken from the config.xml
file.
Validation
The PONumber field is validated using the DefaultPONumber scripted validation.
This does a simple check to ensure that any value entered matches the regular
expression for the customer (either generic or dynamic). Also, the field must not be
empty.
InvoiceNumber
The InvoiceNumber field holds the invoice number found on all invoices. This field
contains several areas of enhanced logic, which will be described in this section.
Locators
The InvoiceNumber field contains the following locators:
ƒ KBo – The KBo locator is a standard order group locator. It attempts to find
order information from a document using both generic and specific
knowledge bases.
ƒ IHL – Invoice Header Locator uses specific and generic knowledge bases and
attempts to retrieve header information such as the invoice number and date.
ƒ SL_SetRegEx – This script locator provides the first of the enhanced logic for
this field. The FL_InvoiceNumber_RegExp which will be discussed next
contains 2 regular expressions, one of which is dynamic and the other a fixed
generic expression. If a regular expression has been set in the supplier
