X3 product update 8 patch 2

Not managed inventory items can be added to a production BOM but when creating a work order an error message is displayed and the not managed item is not added to the work order.

Is this a restriction or is there a configuration setting that would allow this? My understanding is that version 6 and earlier allowed this functionality.

The customer has many miscellaneous items e.g. labels, packing materials that they want to show up on the work order but do not want the overhead of managing these items in inventory.
