Business logic is created and stored with the cube on a server by using rules, ensuring all users have the same calculations in their analysis.
Every cube has a rule file associated with it. It can be found in the Model Design pane below the cube name.
For additional information on rules, please refer to the Reference Material found in the online help or the IBM Cognos Users Guide. The IBM Cognos TM1 Rules Guide is also a source of more in depth information.
