What are Orphan Tasks?
An orphan task is a study task that is not assigned to a study arm. Orphan tasks will not activate to participants in a study – even if there are activate or expiration rules.
To correct the issue, and place the task back in a situation in which the task will activate to participants, Click on the orphan task and edit the “Activation and Expiration” rules.
Assign the task to at least one arm and the task will no longer be an orphan task.
