As a PM, I can update control data from microsoft project

Project managers, or any other management role (PMA, PMO, PfM, PgM), can import schedule and cost tracking data from Microsoft Project®—other scheduling tools like SmartSheet, Primavera, ProjectLibre, etc., can export data as this XML format. If you use some of these tools for performance tracking, you don’t need to repeat the same process in  PMPeople.

Alert for Update can be seen at CONTROL > Control Scope, Control Schedule, and Control Cost.
