Preserve Minimum Activity Float
Preserve minimum activity float field
The minimum amount of total float time expressed in hours that you want to maintain for each activity during leveling.
This setting limits the amount of float an activity can use when being delayed in order to level the schedule.
For example if the float for an activity is 5 days and you set the value of this field to 2 days (or 16 hours assuming 1 day equals 8 hours) the activity cannot be moved more than 3 days.
You can specify any unit of time, for example
2w or
3d, and P6 will convert it into hours for you.
