When you are using a CcotcfBl it appears that it does not have a base table. So, you won’t be able to use views related to that. 

Technically, if you want to find whether that logical unit has a base table, you can use following code to check.
 

begin
  -- Call the function
  :result := dictionary_sys.get_base_table_name(‘CcotcfBl ‘);
end;

please execute above statement  in a PLSQL Test window and check whether it is a base view or not.
