Once can remove the series and states produced in some task run from the central database by shortening their expiry time in the Forecast Manager's "Forecast Expiry Times" pane. Just select the task and press either the Delete button in the top right corner. This will shorten the expiry time so that it ends at the current time. At the next rolling barrel run, the data will be removed. See the user manual the 07 Forecast Manager for more details.
N.B. the deletion may cause some broken relations within the database. A reindex activity will repair that, but this is typically run only once per day. If one needs the relations fixed earlier, one can manually start the reindex activity from the Admin Interface System Control page.
