This is, unfortunately not in standard, but I will send a feedback to the R&D team to evaluate including that in a future version.

Hey there! Managing multi-level BOMs in Odoo can be a bit tricky, I know! You're gonna want to look into the Manufacturing module. There's this feature called the "Unbuild Order." Now, it doesn't directly show missing components. But hear me out. First, you gotta create your Product Tree using all the BOM levels. Then head over to the manufacturing orders section. You'll find options to check availability, which is pretty neat. This'll help you see what’s in stock versus what's needed and what's missing for the production run.

Another thing: try custom filters in your inventory to get a quick look at stock levels for components tied to your BOMs. It’s manual, sure, but you'll get a real-time picture. It's more about using Odoo's existing tools creatively, ya know? I had to tweak this once myself, and it made things smoother. If you need more customization, check out Odoo Studio for reports that fit your setup better! Teh stuffs all about figuring out the optimal workflow, can take some tetsing, but definitely worth it.

That is one of the good questions it is so hard to track down all the bom material
