To perform this action, the caller must have privileges on the entity that is specified in the entityName parameter and access rights on the records that are specified in the entityId and relatedEntities parameters. For a list of the required privileges, see Delete message privileges.

Notes for Callers

This method removes multiple associations in one transaction between the record that is specified by the entityId parameter and each record in the relatedEntities parameter for the relationship that is specified in the relationship parameter.

For a one-to-many relationship, this method clears the ReferencingAttribute in the related record to the value of entityId.

For a many-to-many relationship, this method deletes a record in the intersect table for the relationship. The intersect table name is defined in the IntersectEntityName property for the relationship.

For more information about the exceptions that can be thrown when this method is called, see Handle exceptions in your code.
