EC-CS: how to delete a consolidation unit or consolidation group?

Hello,

How do I delete a consolidation unit or consolidation group in EC-CS? I can see create/change/display (CX1M, CX1N, CX1O) consolidation unit but I do not see a transaction for deleting a consolidation unit or consolidation group? In CX1X I can delete a unit from the hierarchy but that does not delete it from the system?!

Thanks for your reply!
