Removing subgroup node from Cost Center hierarchy

Hello friends,

I need to REMOVE (<b>not DELETE</b>) a cost center group ( a sub node) from the standard hierarchy (OKEON)

I tried to remove as per SAP help option, link as follows:

http://help.sap.com/saphelp_47x200/helpdata/en/5b/d2200743c611d182b30000e829fbfe/frameset.htm

But i couldn't find the 'Remove' option any where in Edit>Selected entry>Remove, its 4.7 system. I checked with other SAP systems also, there is no option like that. Any one worked with this Option?

Any help is appreciated, points will be rewarded.

thanks
