When you show the report in "Reports", you will see two menus for saving snapshots in the Home tab.
1): XLSX snapshot
2): XLSX OLAP snapshot
Since we expect users not to make export operations, the role permission "ste_reports" has been changed to read permission. As a result, I could disable the menu of (2) but of (1).
I would like to see additional right or optional features to disable the menu of (1).
We changed the title to "Disable Excel export from Jedox Web" from "Disable of XLSX snapshot using rights object" to better reflect your request.
