Kofax ReadSoft Invoices validates a field after interpretation and each time the field changes value during verification. If a validation fails, the field receives an error status and Kofax ReadSoft Invoices prompts you to manually correct the field value before the field and the invoice it belongs to are complete and ready for further processing.

You can use a table, or tables, to validate a single item field if there are a limited number of acceptable values for the field.

There are two ways to do this:

• Specify a validation table. This way is appropriate if all acceptable values for the field can be listed in a table. Kofax ReadSoft Invoices searches for the interpreted value in the table. If the value is not found in the table, then the field receives Validation error status and is displayed in Verify.
• Validating field values using a connection table. This way is appropriate when the list of acceptable values for one field is dependent on the value of another field.
