I'm now recreating our development system from an offline backup of our production system.
I have created a new client (150) and I'm currently deleting client 100 to get rid of all its data (almost 3TB) and leave the DEV system with only the customizing.
However, this process is taking too much time and after almost a complete day is still on the A* tables.
Is there a way to speed up the process? For example, delete all contents of some huge tables "where MANDT = 100" on the OS database level?
