Hi Kristian, you would have to join the configuration results options table to the material lines by inventory id. This help article describes the manufacturing tables including the config results tables. The only issue would be an inventory item that is used in more than one feature.
Yes that’s the issue I find when an inventory item is used multiple times not only in multiple features but also within a feature (using different label for the same item). I don’t find any other field such as option line nbr and feature line nbr in production material to use for the join.
When production order is generated for configured item it looks like it does copy process from included options just like copying from BOM when order is generated for non-configurable item so it might not really have a join.
