New KF added to Cube .Will It affect Listcube structure.(Urgent)

Hi,

I added 5 new key figures to the cube,changed the infosource(Communication Struct) and the update rules attached with it.

Will this have any affect to the Listcube structure?

Now as this was not required I need to revert the changes.

What all I need to do so that no other program gets affected and the Listcube structure is as it was before the changes made beacuse there is a BDC dependent on it.
