I know if I stop TM1 Server instance, delete the   }ElementSecurity_mydim.cub  file, and restart the server, this seems to work OK. 
But has anyone successfully used a TI process : 
 CUBEDESTROY  command, then stop/restart the Server instance for these security cubes ?? 
Thanks 
			
			
			
				Hi
I've never tried it personally, but out of curiosity what results are you seeing ?
Do the }ElementSecurity_mydim cubes fail to delete when using the TI command CUBEDESTROY ?
Regards

				haven't tried it yet -- somewhere I read that the SERVER instance has to be DOWN or else the control object won't work So i was wondering if it has been done -- Do not want to make situation WORSE if it goes into some sort of in-between status
