Set Up Validation
Ascent Xtrata Pro User's Guide 219
Note
Do not use formatters to correct OCR results at this state of processing (for
example, to exchange a capital “I” with a number “1” within an amount field). This
should be corrected during extraction, because a field formatter cannot change the
state of an invalid field to valid.
The following formatter types are provided:
• Amount Formatter
Unifies and validates amount formats on the document.
• Date Formatter
Unifies and validates date formats on the document.
• Percentage Formatter
Unifies and validates percentage formats on the document.
• Script Formatter
Unifies and validates any other format types using the Sax Basic script engine.
For more information about setting up formatters, see Extraction
Validation Methods
Validation methods make it possible to implement automatic check algorithms. This
can be by accomplished by using the predefined methods or by creating custom
script methods.
Validation methods belong to the entire project, and have to be assigned to
validation rules to apply them to specific fields. This means that one validation
method can be used in multiple classes in a project, or for multiple fields in the same
class.
Therefore, it is a good idea to set up validation methods in a way such that they can
be shared by as many validation rules as possible.
The following predefined validation methods are provided:
• Standard Validation
• Date Validation
• Regular Expression Validation
• Single Field Script Validation
