Schedule groups are defined in the Define Schedule Groups window and can be optionally assigned to jobs, in the Discrete Jobs window, or to Flow schedules, in the Line Scheduling Workbench Options window.

In Oracle WIP, schedule groups are NOT defined in the Define Schedule Groups window and assigned to jobs or flow schedules as described. Schedule groups are actually defined elsewhere and the assignment mechanism described is incorrect; this appears to be describing functionality that doesn't exist or is inaccurately represented.
