Explanation
"Configurator models are imported from items maintained in Oracle Fusion Product Hub (which is accessed by the Product Information Management work area) that have a Structure Type of Model. Only the optional structure and attributes of the product item are imported, because the required elements of the product item cannot be configured by an end user. The option classes and optional standard items for each model item are also imported.""Configurator models are versioned objects. A model can go through multiple drafts before being released in a series of versions.Therecan be multiple drafts of the same model being modified at the same time, but they must be in different workspaces. A message notifies you if you add a model to a workspace when another draft exists in another workspace. There can only be a single released version of a model with the same effective start date."
