A Mapping task can identify records in a data set that contain unresolved data quality issues. The records may contain errors, or they may contain duplicate information. The Human task organizes the records into one or more task instances that Analyst tool users can work on. The Analyst tool users resolve the issues in the records and update the data quality status of the records.

When you configure a Human task, you create one or more task steps. A task step represents the type of work that a user performs on the records in a task instance. You can assign all task data to a single user, or you can create multiple task instances so that different users can work on different records concurrently.

A Human task starts when a Mapping task ends. The workflow uses the

exceptionLoadCount

output variable from a Mapping task to define the data for a Human task. When all task instances are complete, the data passes to the next stage in the workflow.
