Assume that you use Microsoft SQL Server 2014 PowerPivot. When the business hours are set to end after midnight and the schedule is set to occur "After business hours," the scheduled refresh only occurs every other day instead of every day. When you try to set the end of business hours back to a time before midnight, the scheduled refresh continues to occur at the time that was set previously after midnight.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
