This hotfix also applies to Microsoft SQL Server 2012 Reporting Services.
Symptoms
Consider the following scenario:
-
You are running an instance of Microsoft SQL Server 2008 R2 Reporting Service (SSRS 2008 R2) or SQL Server 2012 Reporting Service (SSRS 2012) in Microsoft SharePoint integrated mode.
-
You have a report or subscription that was authored by a user who no longer has permissions on the SharePoint site collection.
-
A user who has the appropriate permissions on the SharePoint site collection tries to open the report or subscription.
In this scenario, the user cannot open the report or subscription. Additionally, the user receives the following error message:
Report Server has encountered a SharePoint error. (rsSharePointError)Object reference not set to an instance of an object.
Additionally, the following exception is logged in the report server log file:
