Business rule validation

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

When you use a business rule, document or folder variables are used as initialization parameters. Before using Business Rule validation, configure a Boolean and a String variable as outputs. The Boolean variable will indicate whether the validation succeeded, and the String variable will display a runtime message if validation fails.

In a document type, you can add validation to columns in a table using a business rule, for example, to check Col 1 (No of items) * Col 2 (Price) = Col 3 (Subtotal).

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

While using Business Rule validation:

  • If the business rule does not have the correct output, the following message appears: "The business rule does not have the correct outputs. It must have a Boolean and a String output defined to be used for validation."

  • If the business rule has the correct outputs, the business rule inputs are displayed.

  • For each input, you can map a field, system property (of the document/folder/field), or static text.

  • If the business rule has a document variable as an input, you can map the instance ID system property.

  • You cannot delete a field that is in use in a business rule.
