Normally, when a user (accidentally) deleted a Selected Data Extension that is being used inside a selection, the user will not be able to access the selection any longer.
However, DESelect has implemented a feature that will make it possible to automatically fix a broken selection. In this case, a user still has a chance to access a broken selection.
DESelect will fix a broken selection if the Data Extension that was deleted was replaced with a new one with the same external key and fields.
When accessing the selection, a user can see an indication that DESelect is fixing the selection. The user will be notified about the successful fix and indicate which Data Extension was replaced. Otherwise, the user will also be notified in case the selection cannot be fixed.
