Assume that you have a report that connects to a SharePoint External list, and then you set up a Microsoft SQL Server 2012 or 2016 Reporting Services (SSRS) subscription for the report. In this situation, the subscription fails to run, and you receive the following error message:

Microsoft.ReportingServices.ReportProcessing.ReportProcessingException: Query execution failed for dataset 'DatasetName'. ---> Microsoft.BusinessData.Infrastructure.BdcException: The shim execution failed unexpectedly - Proxy creation failed. Default context not found.


This issue occurs because the SPServiceContext or SPServiceContextScope object is never created.


This issue is fixed in the following cumulative updates for SQL Server:

       Cumulative update 8 for SQL Server 2016 SP1

       Cumulative Update 8 for SQL Server 2012 SP3
