Use

You can use this finite scheduling mode to schedule or reschedule an operation in an existing schedule on the desired date , even when there is no slot for this date, or the slot is too small. If necessary, the system creates a slot that is large enough by shifting the neighboring operations on the resource in both directions.

You can only use this scheduling mode for single-activity resources that are to be finitely scheduled. For more information about finite and infinite scheduling modes and resources, see Finite and Infinite Scheduling .
