You are a project manager for an organization that uses Project Server 2013.
You create a complex schedule that has many segments which are divided by your organization's departments and external vendors. The duration of the schedule is 18 months. After six months, you learn that a different department may do some of the upcoming work.
While upper management decides which department they need to perform the work, you realize that your schedule has numerous assignments that now may be done by another department. You do not want to delete the assignments because you have many inter-dependencies among these tasks and the rest of your schedule. However, you cannot have resources working on these tasks at this time.
You need to keep your tasks in your schedule so upper management can view them, and you need to ensure that the team members do not work on or update those tasks.
What should you do?
