SYMPTOM:
When commenting has been enabled for Change Journal transactions, users expect that any change to an object will prompt the user with a comment box. When making a change to the Properties of an object, such as the object owner, users are not prompted to enter comments, but the change is still recorded in the Change Journals.
STEPS TO REPRODUCE:

The same behavior is observed when making changes to the properties of project objects such as reports, metrics, etc.
CAUSE:
This is a known limitation with Strategy Developer.
ACTION:
Currently there are no plans to address this issue and it is not scoped for any upcoming scheduled Strategy release.
WORKAROUND:
These changes are still recorded in the Change Journal. “Object properties were modified” is automatically entered into the Comments section of the transaction.
