Usage of a Predefined Indirect Multi-Value Link

If a predefined link exists that's appropriate for use in a multi-value link (MVL), and if the originating business component is different from the parent business component, then you can use an indirect MVL instead of a conventional MVL. If a predefined join exists that joins the required parent business component to the parent business component of the link, then you can use the predefined link in the MVL.
