| | Object Data ManagementTo link files to objects such as items, sales orders, or BOMs,
use Object Data Management (ODM) files. At several places in LN, the linked files
are automatically available for related objects, such as a production order.
There are two ways to do this: Direct link If a file is linked to an object, such as an item, and a 'hard
table reference' exists between another object, such as a production order and
the item, the file linked to the item is also available on the production order
by the item reference. This does not cost any performance. Copied link If a file is linked to an object, such as a BOM, and no 'hard
table reference' exists between another object, such as a production order and
the BOM, often the link is copied to the next object, that is, from the BOM to
the production order. This makes performance worse.
From a performance point of view, it is best to use a direct
link. So, in case of the example, it is better to link a file to the item than
to the BOM. ![[...]](../images/tr_tc_p000007_odm.gif)
