An assembly whose BOM was created with reference to a sales order, but whose header material however, is not a component in the multi-level BOM for the sales order item. A detached order assembly is assigned to a sales order but has not yet been inserted into the multi-level BOM for the sales order item.

A detached order assembly has the same structure as a normal assembly, however, it has the following special features:

• It was created with reference to a sales order item.
• Its header material has not yet been inserted into the multi-level BOM for the sales order item.

This means that a detached order assembly has:

• A reference to the sales order and to the sales order item
• No reference to the multi-level BOM of the material that you entered in the sales order item

The components of a detached order assembly can themselves also be assemblies.
