Where Budget › ST tab › Automatic Scheduling

Steps
- In the budget's ST tab turn on Automatic Scheduling.
- Change the dates, duration, a constraint or the predecessors of an item from its form and save.
- On saving, its successors move to respect the links, and floats and the critical path are recalculated.
Warning
It comes turned off so that existing projects do not move by themselves.
Site note
In the Gantt successors always move, whether it is on or off.
It reschedules only once per save, even if many items change at the same time (for example with UPD or an import).
