There are many reasons why a project administrator might want to suppress or delete records on their projects in Shared Shelf.
What’s the difference? Deleting, as you probably guessed, gets rid of the record entirely. Suppressing, on the other hand, only retracts the media file and data from the published environment so it is no longer viewable to end users. The advantage is that you can always return to the record to edit the data or replace the media for republishing at a later time.
For that reason, we suggest that if you want to delete a record, you suppress first so the records are automatically retracted from the published environments.
The process is very straightforward. Learn how to do it on the Shared Shelf support site.
