Perhaps some of you have the same issue.
How to mark unassembled parts in xDX Designer and during BOM Output in Expedition PCB? In Expedition PCB BOM unassembled parts should be marked as "unassembled" or similar.
I know it works with VariantManager. But is there a script/userware available to do it without VariantManger license?
There are lots of discussions on the Communities covering various aspects of this, try searching on 'Exclude from Part List'
