@RMV Yes. You can do this in Settings -> Admin Portal -> tenant settings -> Export Data
You can disable it for the entire tenant, or keep the functionality alive for a group of users while disabling it for others.
You need to be either an O365 admin or Power BI Administrator (Role applied by the O365 admin) in order to see "Admin Portal" under your Power BI settings (wheel icon) on the header.
According to the official documents, "No-one can see or download the dataset." in shared dashboard. So users can export the summarized data. It seems that you can enable this function and it will satisfy your requirements.
Could you please tell me if the solution worked? Please mark proper posts as answer if it worked.
Dataset cannot be downloaded. That is well understood.
However, that's not what I'm looking for.
At each of report, there's an option to export data, then there are 2 options whether to export the summarized or the underlying data. I'm looking for the way to disable (some or specific) user to export the underlying data from report/visualization.
The data we can see from a visualization is summarized (used by the visual). Users can't download dataset from a shared dashboard.
I only seem to have the ability to turn it on/off for the entire organization and would like to add in a specific group of users who can export data, is there some setting I have missed?
