Need to swap a costcenter in all the rules

Hi ,

I need to swap a costcenter with another costcenter in all the derivation , substituion rule, where ever it is used ,
  Swap "A" Costcenter with "B" ( New costcenter) .

How to identify in which and all substituiion , derivation rules this costcenter "A" is used , so that I can replace it with "B" new costcenter

Do we have std program which will help me identify this

Thanks
