The scheduling mode controls how the scheduler assigns resources to this task. In planning mode, resources are allocated before and after the current date. In projection mode, resources are only allocated after the current date. In this mode, any resource activity prior to the current date must be provided with bookings. Alternatively, the effortdone or effortleft attribute can be used.

This scheduling mode is automatically set to projection mode when the trackingscenario is set. However, the setting can be overwritten by using this attribute.
