No. Personal Volume (PV) is the total of your personal purchases.
Additionally, only purchases made by members count as your four (4) 1st generation, and sixteen (16) 2nd generation sales required to earn the Star Bonus.
Example: You have 4 Personally Enrolled Members (PEMs). None of them have personal purchases. They all have at least 100 points in Retail sales. None of them would count toward the 4 you need for the Star Bonus because they do not have orders themselves.
