The Exception Configuration panel provides greater control over how exceptions are managed in DvSum. By customizing these settings, users can streamline exception handling, reduce alert fatigue, and improve traceability.

This article explains the purpose and functionality of the Exception Configuration panel and how to use it effectively.

Accessing the Exception Configuration Panel

To access the Exception Configuration panel:

1. To configure exception settings for a rule:
2. Navigate to the Dictionaries > DQ Rules.
3. Choose a rule from the listing page.
4. Go to the Data Quality tab.
5. Click on Edit to open the rule settings.

1. Select the Notifications section from the left panel.
2. Scroll down to locate the Exception Configuration panel.

Exception Configuration Options

The Exception Configuration panel includes the following options:

Alerting Exception Files

• When enabled, this option generates exception files during rule execution.
• These files can be used for auditing or further analysis.

Exceptions to Include

• All Exceptions: Includes all exceptions identified during the rule run.
• New Exceptions Only: Includes only exceptions that are new since the last execution.

Email Recipients

• Allows users to define who should receive exception alerts.
• You can select from default email groups or specify custom recipients.

These recipients will receive the exception notification email when the rule is run.

Enable Exception Tracing

Enabling Exception Tracking is required to identify and differentiate between new and existing exceptions during rule execution.

This feature uses a key field (e.g., customer_id) to trace recurring exceptions across multiple runs. Once enabled, users can easily spot new exceptions, which are typically the primary focus during data quality reviews, along with the existing exceptions.

Note: After enabling Exception Tracking and executing the rule, additional metadata columns will appear in the Data tab to support exception analysis.

New Metadata Columns in the Data Tab

When Exception Tracing is enabled, the following columns are added to the Exception Deep Dive view in the Data tab:

• DV First Observed – Timestamp of when the exception was first detected.
• DV Status – Indicates whether the exception is New or Existing.
• DV Age – Shows how long the exception has existed since it was first observed.

These columns help users monitor exception trends and prioritize remediation efforts more effectively.

Status filter has been added, allowing users to quickly switch between viewing All, New, or Existing exceptions.
