Business rule validation method

Use the Business rule validation method to create complex validation logic.

When you use a business rule, the document or folder variables are used as initialization parameters. If the business rule has a document variable as an input, you can map the instance ID system property. The selected business rule must have the following variables as outputs:

Boolean: Indicates whether the validation succeeded.
String: Displays a runtime message if validation fails.

In a document type, you can add validation to table columns using a business rule. For example, create the following rule on a table field:

Col 1 (No of items) * Col 2 (Price) = Col 3 (Subtotal)

When validation is performed on the document using this rule, each row of the table is validated. If Row 2 has an incorrect calculation, then Col 3 for that row is invalid. See Add field validation rules for a document type.

Child documents or folders do not inherit validation rules.
You cannot delete a field that is in use in a business rule.

Configure a business rule validation method

Open the extraction group and select the document type for which to define a field validation rule.
On the properties panel, click the Field validation tab.
Click  for Validation rules.

The New validation rule dialog box is displayed.

Select Rule makes uncertain extraction results valid to override the execution of validation rules when a field is not extracted confidently or is modified. (Default: Clear)
On the Business rule list, select a business rule to use in the field validation.

A list of business rule input parameters appears.
In the Value field of each input, map the document fields or system fields using dynamic or static values.
