When accessing an IT Analytics report, the error "An error has occurred during report processing. Query execution failed for dataset 'dataset_name'." occurs.

An error has occurred during report processing. (rsProcessingAborted)
       Query execution failed for dataset 'dataset_name'. (rsErrorExecutingCommand)
             For more information about this error navigate to the report server on the local server machine, or enable remote errors

A custom data class has been added incorrectly to an IT Analytics report. This can be found by accessing the modified report directly on the SQL Server Report Server (SSRS) and a full explanation of the error then occurs:

An error has occurred during report processing. (rsProcessingAborted)
       Query execution failed for dataset 'dataset_name'. (rsErrorExecutingCommand)
             Invalid object name 'Inv_custom_data_class_name'.

Remove the custom data classes from the dataset's properties and any embedded SQL in the report while using Microsoft Report Builder and then save the report.
