When exporting to P6, Open Plan, or MS Project, any activities or milestones placed on planned-dates (between their early-start and late-start) will be pulled back to their traditional CPM early-start dates. In order to maintain a comparable network, constraints must be applied to any activities and milestones starting on planned-dates. This can be accomplished using a filters.
