SSRS Report Builder 2.0 - Error during processing

The Issue

After modifying a report and on running it, Report Builder 2.0 returns the following error:


An error occurred during local report processing.
An error has occurred during report processing.
Query execution failed for dataset 'DataSet1'.
The variable name '@GroupName' has already been declared.  Variable names must be unique within a query batch or stored procedure.
The Quick Fix
  1. Return to the Design interface of Report Builder 2.0 for the problematic report:alt

  2. Right-click on the reported DataSet (in my case: DataSet1) and select 'Dataset Properties' alt

  3. Select 'Parameters' and click on the duplicated field alt

  4. Click on the 'Delete' button and you should be left with just:alt

  5. Test and run your report :c)
