identifierValue
The value of the identifier.

lobSystemInstance
The LobSystemInstance object.

Valeur de retour

An entity instance.

Remarques

This form of the API works when there is only one Identifier that is required to uniquely identify an instance of the entity.

Exemple

This example shows how to execute a SpecificFinder method on the Product entity in the AdventureWorks2000 sample.

Prerequisites

Ensure a Shared Service Provider is already created.
Replace the constant value EnterYourSSPNameHere in the code with the name of your Shared Resource Provider.
Make sure the LobSystem object and entity names referenced in the example exist in the Business Data Catalog. Use valid names.
