Activation of Archiving object

Hi Friends,

Please Can any one  tel how to activate the archiving object. i.e. if we enter the archiving objects (MC_S033 & MC_S034) in SARA i am getting the message like archiving object is not available ( I heard that we need to do some BC settings but I am not aware of this settings)

Please help us to activate the same.

Thanks,
