This hotfix applies to Microsoft SQL Server 2012 Reporting Services (SSRS 2012) and SQL Server 2014 Reporting Services (SSRS 2014).
Symptoms
Consider the following scenario:
-
You configure Microsoft SQL Server 2012 Reporting Services (SSRS 2012) or SQL Server 2014 Reporting Services (SSRS 2014) to run in SharePoint Integrated mode.
-
You have a report together with parameters that have expression-based default values.
-
You create a subscription for the report.
