Auto Entry Ispec and its instance
If you export only the Auto Entry Ispec without selecting its instance and import the resultant model file to a new model database, then only the Auto Entry Ispec is available in the new model database.
Note: If CUST is an Auto Entry Ispec in your model, the instance Cust_AutoIspec is created and placed under AutosForIspecs folder.
If you export only the instance of the Auto Entry Ispec and then import the resultant model file to a new model database, the instance is available in the new model database. Since the Auto Entry Ispec is referred by its instance but is not present in the model file and the database, so an unresolved element under the Segment with a green question mark is created.
Note: If both the Auto Entry Ispec and its instance are exported and imported to a new model database, then these elements are added correctly under their respective owner.
