Creating a rotating schedule is good when you have a rolling schedule in place. This function lets you copy a schedule you have created for the period you want.
Choose a period for which you have entered the schedule that should be repeated (must be weekly period)
The start date will by default be the day after source date, and how many copies you want a copy. (To copy one year ahead, enter 51 copies if your source is one week)
