Use

The following cardinalities are possible:

  • 1:N

    This relationship is mandatory. Any number of entities of the To-entity type can be assigned to an entity of the From-entity type.

    This cardinality is valid for relationships with the relationship types Leading, Qualifying, and Referencing. The following applies to referencing-type relationships: The From-entity type is a required attribute of the To-entity type.

  • 0:N

    This relationship is optional. Any number of entities of the To-entity type can be assigned to an entity of the From-entity type.

    This cardinality is valid only for relationships with the relationship type Referencing. The From-entity type is an optional attribute of the To-entity type.
