As you have seen in the FYI approver pattern with list builder – name and expression section, the task gets assigned to the same user multiple times. This holds true for other patterns too. However, Oracle BPM offers the task aggregation mechanism that will enable you to configure how often a user can see the task.

For the same task metadata that you created in the FYI approver pattern with list builder – name and expression section, as it's a repeating stage, click on the stage and then on the Task will go from starting to final participant link on the aggregate section in the task metadata. This will open the Assignment and Routing Policy dialog box. Click on the Assignment tab.

In the task aggregation drop-down list, select STAGE. Save and execute the process. This time, the task will get assigned to the user once. This means that the user will see the task only one time in the stage.

The task aggregation, when defined as none, indicates that there is no approval...
