RSECADMIN: automatic generation of profiles

Hi,

I am generating profiles automatically via RSECADMIN -> Generation. This works fine.

Some questions to this:

1. how can I delete a bunch of profiles at once?
2. I am using DSOs 0TCA_DS01 - 3 via CSV-files. DTP from PSA to DSO is running in delta mode. When I load a delta dataset to these 3 DSOs what will the "Generation" functionality in RSECADMIn do? Will it generate only the profiles from the delta or all profiles again that are in the DSOs?

Thanks!
