I am planning manufacturing for a range of products (bags) that share some common components.

To simplify BOM management, I'm trying to create kit/phantom BOMs for those components. So the BOM structures would look something like this:

Product: Large, Green Bag BOM type: normal BOM line 1: Component for large green bag only BOM line 2: Components for all large bags

Product: Components for all large bags BOM type: sets/phantom BOM line 1: Component for large bags only BOM line 2: Components for all bags

etc. I want to achieve a single manufacturing order for a large green bag containing all the required components. But I get a manufacturing order shown just the items from the first BOM

Even more confusingly, when I look at the Large Green Bag product in the "by BOM structure" view, the various sub-BOMS are described as "normal" even though they we built as "phantom" .

Do I have to change some other setting on the sub-products to make them appear as kits in the main BOM?
