FIX: The .csv file contains field separators when you export a report that has a tablix that has no data in SSRS 2012 or SSRS 2014

Symptoms
Assume that you have a Microsoft SQL Server 2012 Reporting Services (SSRS 2012) or an SSRS 2014 report that has a tablix that will return an empty dataset, and you set the "NoHeader" attribute in the RsReportServer.config file for CSV rendering. In this situation, when you export the report to CSV format, the .csv file contains field separators.

Note The expected behavior is that the CSV output is blank as it was in the earlier versions of SSRS.
Resolution
This issue was first fixed in the following cumulative update of SQL Server.

Cumulative Update 1 for SQL Server 2014 SP1

Cumulative Update 6 for SQL Server 2014

Cumulative Update 3 for SQL Server 2012 SP2
