I have a development org with a quite complex object structure and a ton of demo data. To refactor thr structure I want to get rid of all this data.
My first thought was to use the new "Truncate" button on objects, but that would mean I would have to delete child records first. For a structure like this this is not something you just calculate in 5min.
Is there another way to do this? I also tried the "Delete All Data" but that gave up as my org has too much data.
