Description types are used in the Sales Configurator, the Production Configurator, and the Objects module.
The different description types are defined in the Description types file. The description types are then used in the Features file:
On the Features tab of the Basic data form, one description type has to be set as the default. During the configuration of a part or object, only the descriptions of the base type are shown for both the feature and the options. For example, only the French versions of the features and descriptions might be displayed. The reason for this is that a feature such as 'Color' can have more than one description (for example in different languages), as well as multiple options (Red, Green, Blue).
