In the Gantt and Timeline views, a milestone item appears as the item's name, preceded by a diamond icon.
% Complete rollups aren't available for parent tasks that contain subtasks that are milestones.
In Gantt view, create a milestone
The following steps demonstrate how to create a milestone in Gantt view.
If you haven't already activated dependencies on your sheet, activate dependencies via your sheet's settings.
In Gantt view, milestones cannot be shown unless you activate dependencies; otherwise, all items are displayed as bars.
Add an item to your sheet, and set the item's Duration value to zero, and set the item's Start Date and End Date to the same date.
If neither the item's Start Date nor End Date is set, and you set one of them, Smartsheet automatically sets the other date field to the same date.
A diamond icon precedes the item's name, marking it as a milestone.
In Timeline view, create a milestone in a sheet with dependencies
The following steps demonstrate how to create a milestone in Timeline view.
- If you haven't already activated dependencies on your sheet, activate dependencies in your sheet via the sheet's settings.
- Add an item to your sheet, set the item's Start Date or End Date, and set the item's Duration to zero.
Smartsheet renders the item as a milestone.
In Timeline view, create a milestone in a sheet without dependencies
In Timeline view, if dependencies are deactivated in your sheet, you can still create a milestone.
If your sheet has Start Date and End Date columns, add an item and set only the Start Date or the End Date, but not both dates.
If your sheet has only one date column, then all the items in the sheet appear as milestones.
