When you create your import mappings from the target system, you can automatically generate validation rules that are set on the import definition. By selecting this option, you allow the system to determine which rules it will run for each action, saving configuration time. You can configure which rules are automatically generated for each action in the Data Validator system options. The actions and rules that appear are configurable. For more information, see Rule auto-generation model.
For more information about the system default options, see Set Data Validator Default Options.
