A report that is configured to write to unmanaged disk and outputs a .csv file is generating the following error message:
"Operation not yet implemented"
The error occurs when there is no data for this report to return. This occurs when no database records are being returned by the report.
To work around this behavior, ensure that the report contains some data in it.
