Rule Occurrences tab of a data quality rule template

When you open a rule template, the Rule Occurrences tab shows all rule occurrences that are manually created and automatically generated from the rule template. A rule template is the governance representation of a data quality rule that you want to run on some data elements. The rule occurrences are the individual scores of data quality rules that are run on each data element.

Viewing latest preview of failed rows

You can view the latest data preview of failed rows for a particular rule occurrence in the Rule Occurrences tab of data quality rule template. By default, the system can retrieve the data from a maximum of 100 failed rows.

To view the data preview of failed rows, the following prerequisites apply:

- Ensure that the organization administrator has enabled the Preview Data feature privilege for your user role in Administrator.
- To perform drill down, and to view the Preview of Successful Rows and Preview of Unsuccessful Rows in a Data Governance and Catalog scorecard, you need the following privileges for the Data Profiling service in Administrator:

▪ Drill Down
▪ Query - Create
▪ Query - Submit
▪ Data Profiling Results - View
▪ Sensitive Data - View

For more information about the privileges in Data Profiling, see Data Profiling feature privileges in the Administrator help.

- The data quality rule is run at least once, and data quality scores are available to retrieve the data preview of failed rows.
- The primary data element is associated with the rule occurrence and is not of a hierarchical type.
- The rule occurrence is associated with a rule template.
- Data Governance and Catalog is integrated with a data quality application and the Data Quality option is enabled in Metadata Command Center for the catalog source.

In the Rule Occurrences tab of data quality rule template, click the Action menu for the rule occurrence for which you want to view the failed rows and select the Preview of Failed Rows option. The failed rows for a particular rule occurrence are displayed that are generated from the rule template.

Note: In Metadata Command Center, when you run a catalog source with the Agent Cache option enabled in the Cache Result field in the Data Quality capability, and then run a data quality job in Data Governance and Catalog, the preview of the failed rows is automatically generated. Thus, when you click the Preview of Failed Rows option, you can immediately view the failed rows table. However, when you run the catalog source with the No Cache option enabled in the Cache Result field, a preview job is triggered in Metadata Command Center. As a result, the preview of the failed rows takes a longer time to be generated.
