Examples

The following example demonstrates how to use the Disassociate(String, Guid, Relationship, EntityReferenceCollection) method to remove an association or link between records.

/// <param name="service">Authenticated IOrganizationService instance</param>

static void DisassociateExample(
      IOrganizationService service, 
      Entity target, 
      EntityCollection recordsToDisassociate, 
      string relationshipName) {

      EntityReferenceCollection entityReferences = new();

      foreach (Entity record in recordsToDisassociate.Entities)
      {
         entityReferences.Add(record.ToEntityReference());
      }

      service.Disassociate(
         entityName: target.LogicalName,
         entityId: target.Id,
         relationship: new Relationship(relationshipName),
         relatedEntities: entityReferences);
}

Privileges and Access Rights

To perform this action, the caller must have Read privileges on the table that is specified in the entityName parameter and Read access rights on the record that are specified in the entityId. Callers must also have Read and Write privileges and access rights for the records referenced in the relatedEntities parameter. Learn more about how to verify access with code.

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 value of the lookup column named as the OneToManyRelationshipMetadata.ReferencingAttribute in the relationship definition.

For a many-to-many relationship, this method deletes one or more records in the intersect table for the relationship which contains the ID of both the referenced and referencing records. The intersect table name is defined by the ManyToManyRelationshipMetadata.IntersectEntityName property in the relationship definition.

You need the intersect table name when you query for the records. However, you only need the relationship name to set the relationship parameter. This name is defined in the ManyToManyRelationshipMetadata.SchemaName property in the relationship definition.

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

Supported tables

You can use this method to disassociate any records that participate in a relationship. The Disassociate message isn't bound to a table.
