I have a report that prints earnings statements for over 4,000 employees. Of those 4,000, 110 are aborting with the error:
The processing of Parent for the tablix 'table 1' cannot be performed. Cannot compare data types System.Int32 and System.String. Please check the data type returned by the parent. (rsComparisonTypeError).
When I run the report in Visual Studio 2008 for an employee that fails on the report server, it runs successfully. I've compared data for a successful employee and a failing employee and don't see anything different in the two.
Has anyone seen this or have any suggestions for tracking the error down?
Thanks,
Lee

The next thing I would do is to look through the Reporting Services trace logs on the server to look for a specific error.

\\Program Files\Microsoft SQL Server\MSRS10.MSSQLSERVER\Reporting Services\LogFiles

We had same issue in our SSRS report.

The issue root cause is not clear but this shows up when you migrate 2005 reports on 2008 or above.

We were able to fix this issue by removing the grouplist for a tablix.

Goto report layout-> select tablix then right click select properties -> move to Groups Tab->

select the grouplist -> click edit button -> Remove or delete Parent Group.

If you have multiple grouplist repeat the above steps.

This should fix the problem.

Hi Grasshopper,

I'm having this issue having moved a report from SSRS 2005 to SSRS2012. I have 2 options to edit this report. One being the Report Builder 3.0 - running from the report server. The other being Visual Studio 2012 (SQL Server Business Intelligence). I can't see how to apply your solution in either case because looking at the Tablix Properties doesn't display a Groups tab. Would you be so kind as to explain what tool you're referring to and how I can get access to the same area. I'm very grateful for any assistance.
