A Human task contains one or more steps. A step is a blueprint for the task instances that the Analyst tool users must work on to complete the Human task. When a workflow runs, the step identifies the data to assign to each task instances and defines the type of work that an Analyst tool user must perform on the data.
You can add the following steps to a Human task:
Cluster step. Configure a Cluster step when you want a user to examine duplicate record clusters and create a preferred record from the values in the duplicate records. The Analyst tool identifies the tasks that a cluster step defines as tasks to correct duplicates.
Exception step. Configure an Exception step when you want a user to examine and fix errors in records. The Analyst tool identifies the tasks that an exception step defines as tasks to correct exceptions.
Review step. Configure a Review step when you want a user to review the work done in an Exception or Cluster step. Review steps are not mandatory. The Analyst tool identifies the tasks that a review step defines as tasks to review duplicates or review exceptions.
You can add a Cluster step or Exception step to a Human task, but you cannot add both. The database tables in cluster steps and exception steps have different structures.
You can add steps in any order. For example, you can add a Review step before or after a Cluster or Exception step.
