NOTE: Data quality rules are not transformation steps. They assess the current state of the sampled data in the Transformer page.
NOTE: As you apply transformation steps to the data, the state of your data quality rules is automatically updated to reflect the changes. If you delete columns or other elements referenced in the data quality rules, errors are generated in the Transformer page.
You can add a rule from inside the Transformer page.
For some rule types, you can create a data quality rule using custom metrics to assess the data quality. You can use the calculated metric type (derived metrics) as a data quality input type and create a metric-based data quality rule. For more information on input types, see Data Quality Rules Reference.
For example, you can create a metric-based rule to find out if the minimum value metric is within the acceptable range. To do this, you can select a
In Range data quality rule, select
Minimum input metric, and other required parameters to create a metric-based rule.
