Drap & Drop for ETL & Report upload
Drap & Drop for ETL & Report upload in Integrator & Report Designer
Drag & Drop has been implemented already for Files Upload in Report Designer. The drag&drop handler also allows to start Data-Driven Modeling (given that it is a matching file type).
If you still would like to see drag&drop support in the UI for Jedox Integrator, please create a new feature request.
