Hi, I was able to reproduce the behavior, when I changed the field name of the Flatten view in the Output tab of the Web Design Studio. In this scenario, I would use the Virtual DataPort Administration Tool which automatically changes the field names of the flatten view to avoid conflicts at run time and also I was able to modify the field name as required. You can refer to the [Creating Flatten Views](https://community.denodo.com/docs/html/browse/8.0/en/vdp/administration/creating_derived_views/creating_flatten_views/creating_flatten_views) section under the Virtual DataPort Administration Guide for more information. Hope this helps!
