In Etere database, you cannot delete an asset which already been scheduled in the schedule list, a scheduled asset also cannot be changed to unscheduled in Media Library.
By adopting the following work-around solutions, you can “hide” the scheduled assets to maintain tidiness of your Etere database:
1.Create a Historical Database, and move all dispensable assets and unwanted assets into this database.
2.In Media Library, set the assets as expired to prevent filtering assets without the “Search also expired assets” option enabled.
