title: The row item structure object corresponding to a line cannot be null
body: <p>I am very new to SSRS and am trying to generate a report using SSRS, I am able to pull the data on to the screen without any issues but when I try to export the data to an excel file, I am getting an error <code>"The row item structure object corresponding to a line cannot be null"</code>  when there is data that spans multiple tabs in an excel. I am able to export to any other formats eg: PDF. After some googling I found that there is an issue with the SQL Server reporting version and Microsoft mentioned that they will release a patch to fix this issue but I dont see that there was any patch.  I am using <code>SQL Server Reporting Services Version 2007.0100.2531.00</code>. Any pointers will be of great help.</p>
