Adding one ESU to multiple type 3 streets.

I am adding the Nation Cycle Route to my LSG but I’m getting an error “NET-0041:group type is exclusive and at least one element already exists in another group of this type”.

Details;

I have an ESU (03642720426438) that is part of a type one street (Pleasington Lane) and part of a type 3 (C619). This also needs to be part of another type 3 for the cycle route (NCR6).

I have created the type 3 describe as NCR6 but at the point of adding the ESU I get the error “NET-0041:group type is exclusive and at least one element already exists in another group of this type”.

Thanks

Paul
