When using some form layouts, the date that is viewable and editable on the form layout itself is not the Sched Start Date field, but possibly the Actual Start or Actual Finish date field. Normally, to change the date on an order, you need to change the Sched Start Date field, or possibly all three.
To change the date on an order properly, right-click on the Appt Time on the order form, and choose the Activity Details option, which will show you the Activity Details screen. There is a Date/Time tab here where you can edit the Sched Start Date/Time, Actual Start Date/Time, and Actual Finish Date/Time. Then click OK. This is how to properly change the date on an order.
