## About this task

To avoid creating a match rule from scratch, you can duplicate an existing one and work around its metadata and definition to have a new rule.

## Procedure

1. In the DQ Repository tree view, expand Libraries > Rules > Match.
2. Browse through the match rule list to reach the rule you want to duplicate.
3. Right-click its name and select Duplicate.

   The duplicated rule is created under the Match folder in the DQ Repository tree view.
4. Double-click the duplicated rule to open it and modify its metadata and/or definition as needed.
