Exception Management Overview
An exception is a record that contains unresolved data quality issues. The record might contain errors, or the record might contain redundant or duplicate information. You can review and fix exception records in the Analyst tool.
To work on exception records, you open a task. A task identifies a set of exception records in a database table.
The Start workspace in the Analyst tool displays the tasks that you can work on. The workspace might contain tasks from the same database table or from different database tables. When you open a task from the workspace, you claim ownership of the task, and you must resolve the data quality issues that the task specifies.
