Case Specialisation - Data Propagation of circumstanced property
The courseware is a little vague on the requirements for Case Specialisation. It only states:
"On the Details tab, we configured the Data Propagation dialog so that the system propagates the .PolicyState values to a Dispute subcase when it is created."
It's a requirement that the property used to specialise the case needs to be populated. I believe the above needs to be reworded or explain these requirements in the "How Case Type Specialization Works" section.
