Previously model permissions could be set for read, create, update and delete operations. We have extended that list with the 'export' operation. You can now select which user roles are permitted to export for every data model you have. Applying permissions to export works in the same way as the other 4 operations.
The export feature is a basic feature in our largely standardized back-office user interface. What happens when I (as an application user) am not permitted to export data? When you don't have the permissions to export, the button to either use or compose an export definition will not be visible. This will be hidden for those users. However, every user who is permitted to export will see the option. Take a look at the video above that explains this further. Or read this learn article for more information about export and other permissions.
