PPMN_ — AttributedTo could be useful when Occurrences are known

The definition says "The AttributedTo relationship is a kind of AssociatedWith relationship that captures the fact that an Entity was created or transformed by some unknown activity or action of a Party."

However even if the activity detail is known, there may still be value in giving someone specific (out of all those who may have played some role) credit or responsibility for the Entity e.g. in case of support or other inquiries.
