In the Data quality studio parameters, you can enable logging of data quality policy validation rules execution.

Validation rule execution results are logged only when you manually add or change records. Each time a validation rule is executed, an entry is logged.

You can clean up the data quality policy execution log once or in recurring mode.

For example, you want to keep validation history records for one month. Each week, you can do a cleanup, deleting history records older than one month.

The steps of this topic explain how to clean up the validation history.
