Usage of a Predefined Indirect Multi-Value Link

If a predefined link exists that is appropriate for use in a multi-value link, and if the originating business component is different from the parent business component, then you can use an indirect multi-value link instead of a conventional multi-value link. 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 multi-value link.
