By default the part properties generated by the The Activity Decomposition Wizard (for the object flows and actions owned by the decomposed Acfivity) are owned by the generated Associations, which Associations are owned by the same Namespace which owns the generated decomposition diagram.
The following diagrams show the default result and how to fine tune it. The first diagram shows the simple Activity to be decomposed. It includes two CallBehaviorActions and an (knowingly incorrect) "elided Pin" ObjectFlow, which is incorrectly represented by MagicDraw UML (and many other tools).
Make sure the general project option Enable dot notation for associations is on (true)
so you can see ownership of a Property on Association end by a Classifier.
