Vesys will allow different part numbers for schematic & harness. In order to update this you have to do resynchronise the harness after updating the schematic.
For scaling the harness, as per my understanding there is no option to scale the harness directly. For that you have to export the harness into DSI or XML file, then import the file into new non scaled harness.
This seems like migration from vesys classic to 2.0
