--- SOLUTION ---
I found a solution for that problem:
1. Build your Bus in the Buseditor and make sure it is in the workspace
2. Use this bus as output signal definition for the "bus creator"
3. Set the bus in the bus creator as "nonvirtual bus"
4. Also define the in and Outputs of the "variants" for the "variant subsystem as nonvirtual bus
works! attached the model again! have fun
