Object type & is not possible as source object type of relationship
Help Document

Diagnosis

The object type entered is not allowed as the source object type in a relationship. The object type is defined in table T77EO as an external object type, for which no inverse relationship is allowed. This means that the object type may only be used as the target object type in a relationship, not as the source object type.
