Hello Sasha,
Any user with at least “ANALYZE” permissions is able to create reports, more information about roles can be found in our documentation:
https://www.gooddata.com/docs/cloud/manage-organization/manage-permissions/set-permissions-for-workspace/
Regarding who can view which reports, this can be managed via the share dashboard option described here:
https://www.gooddata.com/docs/cloud/create-dashboards/share-dashboards/
Limiting which sections of the workspace a user can access is managed via the user permissions, for example, if you assign a user the “VIEW” permission, they will be able to see the dashboards dashboard creators have shared with them, but Analytical Designer will not be available. On the other hand, if you are referring to the data itself, this can be managed via data filters:
