Links and Milestones

To create the architecture of your project, you have the option of linking tasks together and creating milestones.


Links are used to create a succession of tasks. They can only be created in the When view of a project, or in the multi-project Gantt view.

Use the links between the tasks if the tasks must be carried out in a specific order. For example, if task B cannot start until task A is completed.

Project > When view: Hover over a task to display the starting point of a link at its end mceclip0.png. Click on this circle, then use drag-and-drop to bring the end of the arrow to the task to be linked.

You can create as many links as you want and the tasks will be automatically organized accordingly.

Click on a link to remove it.

Task > When tab of the detail panel: At the bottom of the panel, you can see if the task is linked to another task.

Warning: once the task is linked, any modification of the planning on one of these tasks can have an impact on the other linked tasks and therefore the overall planning of the project.

Note: You can only create a link between two tasks if they belong to the same project.


Milestones are important steps in a project. They mark a deadline, a stopping point in a process. It can be a delivery date, a step requiring validation…

Task > When tab of the detail panel: at the bottom of the window, check the “Milestone” box to activate it.

A milestone task is represented with arrow ends in the planning views mceclip1.png. Tasks linked to a milestone cannot reschedule the milestone. In a succession of tasks, milestones will be taken into account when you reschedule linked tasks. If you try to move a milestone task in one of the planning views, an orange border will appear to indicate the limit not to be exceeded.
