How do you change the column order, which is used when exporting a result list to a CSV-File?

The CSV-File, which is generated, is using the field order from the result list. That means, that you have to alter the field order in the corresponding result list (File Cabinet > Dialogs > Result Views).
Please reload the Web Client afterwards, or if necessary delete the browser cache.

Note: The manual arrangement of the column order in the Web Client is only for customization purposes and does not affect the output of the CSV-File.
