You are a project manager for an organization that uses Project Server 2013. You have the appropriate permissions to set all baselines. Your project experiences a scope change, which requires you to add tasks to the end of the schedule.
You need to retain historical information for both completed and in-progress tasks but create a baseline that includes the newly-selected tasks.
You check out your schedule in Project Web App (PWA) for editing and select the newly-added tasks.
What should you do next?
