I am reporting this as a problem, because the query report is a workaround only.
We were informed that the SDP admin cannot see all scheduled reports in the user interface by design. This is very bad situation, when SDP admin don;t have any control on scheduled reports e.g. by technicians who are no longer working.
Please create query reports which can provide the below information across ALL scheduled in SDP reports:
Report name \ Next Scheduled Date \ Recipients \ Techncian Name (owner)
