      U Column in the List of business rules
   When you apply a business rule to an object, the U (Used) column beside this business rule is automatically checked in the List of business rules to indicate that the business rule is used by at least one object in the model. The U column allows you to visualize unused business rules, you can then delete them if necessary.
