Solution for changing value characteristic into InfoCube

hi guru,

I have a standard InfoCube with historical data (so I cant' do an Init to reload data!).

I must change a value for a specific charatcheristic. Have you got any solution alternative to copy data in twin InfoCube and come back data into the origin Infocube replacing the data trought the update rule??

I have tried with remodeling toolbox (as of 2004s) but I couldn't do it.
