I want to know if it's possible to add a task to two timelines. I have a task list on a project site that has several timelines to display the tasks by department, but I want to also have a timeline to roll some of the major tasks together on a combined timeline.

Is it possible to add one task to multiple timelines or no?

    I can't think of a way to do exactly what you're asking. But you might be interested in using subtasks. You can create major tasks and then create sub-tasks related back to a major task.

  • thanks, but I'm already using sub-tasks. What I'm hoping to do is use multiple timelines to visually show subtasks by department/group and then roll up the major tasks onto a general timeline. My problem is that the major tasks (as well as as the sub tasks) are already on other timelines.

  1. Each Task List has its own "Timeline" that can only be seen in a default style view when the timeline check box is checked.
  2. there is a web part that you can connect to one task list called Project Summary found under the content roll up section that is a timeline.

multiple task lists can not display in one time line, however you can make one page with a couple timeline or "project summary" web parts that all point to their own task lists to help users see it all.
