How to add Business rule to control

Dear All,

Am trying to assign Business rule to control ( GRC 10 -  process control )

Am doing it in

Rule Setup -> Continuous Monitoring -> Business Rule Assignment.

Even though Business Rule in Active status , i cant able to see in Business Rule Assignment.

Whether i need to activate it anywhere or it needs to be assigned some where.

Please guide me.
