Segments which are used in Report Builder Reports and ASI slots are showing up in the segment manager - which is great.
The Downside is, that one cannot recognize that they are in use and may accidentially delete them which lead to failure in the other tools.
-> please autotag segments in use for Report Builder Reports (at least the sheduled ones, which are known by the server), ASI slots and DWH exports ...and everywhere else.
If someone tries to delete them either display an extra special warning or totally prohibit deletion of these segments.
