Description
This button is used to recalculate scheduling. A window opens: simply select an eligible date from the calendar. The dates proposed are those between the current remaining work smoothing start date and the current date.
This button only appears when remaining work has been entered on the project before the last smoothing start date.
The date is grayed out if it turns out to be unselectable: either before the project start date or after the project end date.
