Windchill Attribute Types
Windchill supports five types of attributes:
2. Global
Calculated Attributes and Alias Attributes
Alias attributes and some calculated attributes are derived from the values of other attributes. So these attributes should not be used on Create or Edit clients. If they are used in create or edit layouts, “(Unassignable)” will be displayed. They can be used on UIs that display persisted values of attributes.
Calculated attributes that are based on constant values may be displayed in create and edit clients.
For more information on defining these attributes, see
Creating a New Attribute.
