We have an SSRS Report on SQL Server 2008 R2 SP2 CU3 that is throwing a vague "500 Server error," but only when run against a specific customer record. I ran a SQL trace filtered on the user's Client Process ID while the issue was reproduced, but did not find anything useful. But the SSRS log contains the folowing when the rport was run:System.Data.SqlClient.SqlException: Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.The statement has been terminated.I think it might be useful to run a SQL Trace on the Reporting Server PID instead. But the Reporting Server has about a dozen open processes connected to SQL at a given time. What is the best way to run a SQL trace on specific report that will NOT create performance issues for other users?
