Loading Variant Specifications
This capability is available only to members of the Platform Structures group.
Companies can load variant specifications in Windchill to create new and update existing variant specifications using a command-line utility that can be run from a Windchill shell.
You can also use this application to load a variant specification to create new variant part structures, or update an existing variant part structure based on the updated variant specification.
The input data is provided in a spreadsheet format. The input spreadsheet specifies all information required for creating variant specifications and variants: the configurable part and option set information, characteristics of part and rule configuration specification, and a set of initial choice selections for the Option Filter.
Alternatively, you can load variant specifications by calling an out-of-the-box API.
