Retrieve records for many-to-many relationships using intersect entities

Article
07/22/2016

Applies To: Dynamics CRM 2015

In Microsoft Dynamics CRM 2015 and Microsoft Dynamics CRM Online, when there is a many-to-many (N:N) relationship between two entities, an intersect entity is automatically created. This is true for both system relationships built into the product as well as custom many-to-many relationships. The name of the entity is specified in the IntersectEntityName property in the relationship metadata. The name of the relationship is specified in the SchemaName property in the relationship metadata.

You can use the intersect entities to refine the result set in any query by using the IOrganizationService.RetrieveMultiple method or the RetrieveMultipleRequest message. However, you cannot retrieve the intersect entity records directly by using the QueryExpression class. To retrieve the records in an intersect entity, you must use the FetchExpression class.

Intersect entity metadata

Most intersect entities are simple, containing just the few properties that are needed to provide a link between to two entities in the N:N relationship. If you are using early bound types, you can see an example, in the ContactInvoices intersect entity. This is the case for all custom many-to-many relationships. However, there are several intersect entities that have additional properties that are used for specific functionality for the relationship. To make it easier to write queries by using the special intersect entities, the attribute metadata is provided in the following topics:
