Hi, here is the scenario: I sell a finished product which I designed, made of 3 parts. I control the CAD for those parts and the BOM. Let's say it's a bucket. BOM: - Handle - Pail - Sticker However, the bucket comes in three variations: Plastic, tin, aluminum. So there are 3 BOM's, one for each variation. Now - I don't *manufacture* the bucket, I have someone make it for me. And I don't stock buckets, I have one made and shipped to me each time I need one. When a customer puts in an order for a bucket, say a plastic one, I can easily set it up so Odoo generates a Vendor Purchase Order which gets emailed to my manufacturer. But how do I include the relevant BOM along with it, "just as a reminder" for the manufacturer who I am purchasing my custom order from? (This way I also control revisions of the product, can add new variations, etc. while having the 3rd party manufacturer supply me with the parts). Thanks, David Szego david@szego.me
