Question:
Why is a user unable to create a Workflow for the Clinical User Task Object Lifecycle in Vault?
Answer:
This is working as designed. Since the Clinical User Task is of the User Task object class, it does not have a Lifecycle that can be utilized in workflows. This is because the workflow of the object is controlled by completing the user task.
The only pieces of configuration that can be controlled are the lifecycle and lifecycle states themselves.
