Table to link the change request and the Object i am creating the change request on

Hi All,

      I am looking for tables that can relate the Change Request number with the the Object that i have created the change request on, for Example i am trying to create a new cost center in MDG or changing a Old cost center. IS there any table where if i can give the Change request number and get the Cost center for which the change request is created for ?

I tried USMD120C  change request header table and  USMD1213 - Change request characteristic table.
