Validation methods let you implement automatic checks. You can create several types of validation methods including custom script methods.

To use validation methods throughout a project, assign them to validation rules before applying them to extraction fields. You can use one validation method in multiple classes in a project, or for multiple fields in the same class. Set up validation methods in such a way that you can share them with as many validation rules as possible.

The following validation methods are used to validate single fields:

• Standard Validation

• Date Validation

• Regular Expression Validation

• Single Field Script Validation

The following validation methods are used to validate multiple fields:

• Multi Field Script Validation

• Invoice Field Validation

Manage validation methods as follows:

• Add a validation method

• Modify a validation method

• Rename a validation method

• Delete a validation method

• Test a single field validation method

• Test an invoice field validation method

• Test a multi-field script validation method

• Reorder fields

• Apply a validation rule to a field
