To create association with an inherited entity (without its own primary key) you need to set up ‘virtual ID’.

Create an ID inside the inherited entity and use it as an inverse field. This ‘virtual ID’ will be only used in a visual model, it will not be exported to the definitions, but it will be properly replaced by the inherited ID.
