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.

Prerequisite(s): You have selected the Profiling perspective of the studio.

To duplicate a rule, do the following:


  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.
