# See what a change will move

A planning change that would move a milestone, push an item past an ancestor's **Finish**, or put someone newly over capacity waits for **Save** or **Cancel**.

## When a change is held

Edit **Start**, **Finish**, **Duration (d)**, **Estimate (h)**, **Assignees** or a dependency in item details or in a table cell. A strip lists each kind of impact, such as **Launch milestone moves +4d**.

## After a saved change, a message tells you what it moved

**4 dependent items moved** appears when a saved change moves other finish dates. **Saved with knock-on effects** appears when it moves a milestone, passes an ancestor's **Finish** or puts someone over capacity, with the same lines.

- **Undo** reverses the change while it is your latest.
- **Show on Gantt** shows the first affected item, when a Gantt can show it.

## Dragging on the Gantt

A drag is never held. The tooltip shows the worst impact, and up to four when you pause. Schedule drags too.

## Edits that are never held

Bulk edits, board and mind-map drags, and assistant edits save at once.
