BI Statistics - related

Hi,

In my system recently we have upgrade into BI 7.0 from 3.5...Earlier we used to have a process chain to update the statistics for all 0BWTC_C02/03/04/05/06....

In BI 7.0 most of the above objects are replaced with new objecsts 0TCT_C / 0TCT_VC...

As of now I cannot able to see anyof these info providers in my system... Kindly guide the process for implementing BI Statistics.....

Regards
