It's useful sometimes to add a special character to an attribute in Anaplan. For instance, a special character can further deliniate and mark the name of a list or module to add another dimension to a model's back-end organization. Alternatively, use it in conjunction with a consistent process and include select characters in the name of an action published to a dashboard.
