A task can be assigned a start date. This date will be used for Gantt workmap generation (step 2) and faisibility checks (step 2 either).

In step 1, the start date will have some checks performed :

• Task cannot start after the milestone deadline minus expected duration, if the current task is assigned to a dated milestone.
• Task cannot start after project ends (minus expected duration).
• Task cannot start before project starts.
