This hotfix also applies to Microsoft SQL Server 2014.
Symptoms
Assume that you have Microsoft SQL Server 2012 PowerPivot for SharePoint 2013 add-in installed on a computer. After you apply Cumulative Update 7 for Microsoft SQL Server 2012, some PowerPivot workbooks cannot perform a data refresh operation in Microsoft SharePoint 2013. Additionally, the following error messages are logged in the SharePoint ULS log:Â

Note
-
This issue typically occurs if the serialized length of the data refresh schedule is too short compared to the original length.
-
The issue also exists in SQL Server 2014.
Cause
This issue occurs because the Custom Properties on the Excel workbook are not correctly cleared before you set a new serialized schedule. This causes an extra custom property to remain after you set the new schedule. Therefore, the new schedule fails.
Resolution
Cumulative update information
The issue was first fixed in the following cumulative update of SQL Server.
Cumulative Update 1 for SQL Server 2014 /en-us/help/2931693
