Christian Carlow commented on OFBIZ-5420:
-----------------------------------------
I actually added the BOM variant selection functionality to make the intended functionality of separately pricing BOMs more complete. In retrospect assembly elements probably shouldn't be priced separately.
The company requires assembly items to exist as order items because their custom ERP uses order items to determine future work to be performed rather than relying more a more advanced production run system that exists in OFBiz for determining the same information. Because OFBiz associates mandatory production runs for each subcomponent of the final good, subcomponent work load can be determined based on those mandatory production runs created instead.
On the other hand, assembly items and the assembled item should exist as separate quote items and the default price is used when the unit price isn't specified manually. The problem is that the unit price of assembled product order items shouldn't be set to the default price that was used for the corresponding quote item but instead calculated based on the sum of default price of each assembly component multiplied by the number of pieces needed in order to make the final assembled product. I added the separate BOM pricing functionality to solve this problem but now am thinking that perhaps the problem could be solved without providing separate price field for each BOM assembly.
If assembled items should still be shown whenever they exist as virtual products then it seems a separate method of assembled item unit price calculation would be needed to account for the selected feature additional prices.
I guess this issue should be considered a work in process at this point.

> I have a scenario where a company individually prices BOM elements of assembled products ordered. So if an item is manufactured from 2 component products, the company needs to be able to specify prices for both of the components to made up the total parent product cost.
