Assigning Choices to Service Structure Objects
If options and variants are enabled for your context, you can assign item choices to publication structure objects. Options and variants are enabled in the Preference Manager in the Options and Variants preferences group. The Configurable Module Support preference in the group must be set to Yes to enable you to assign item choices to objects. Note that if you use the Windchill Service Information Manager general product template to create your context, this preference is set to Yes by default. For more information about options and variants, see Windchill Options and Variants Capabilities.
Once options and variants are enabled and configured, you can assign item choices to a structure. Note that an object must also be checked out for the action to be available.

You can view choices assigned to a service structure object on the Attributes tab in the Structure tab. Note that if you assign item choices to a content holder object, those choices are only assigned to the content holder and not to the content associated with the content holder. A content object in Windchill can be associated with a number of different content holders, and each of those content holders can have different item choices assigned to them.
