Actually, I remembered list price of product used in pricing is a functional field anyway, so it is just updating that function. Using lots, you could probably do the whole requirement in less than 200 lines of customisation, maybe a lot less.

Hi,

We've had this requirement for years, except to make matters worse 95% of them also need to be manufactured and each item is also made up of multiple unique items. And in general they all have unique prices. So need to deal with BoM's, Manufacturing etc as well.

Its not too hard using production lots. In fact it would suck not using them I think. Things like doing a stocktake (which unique item is it) would be impossible otherwise, warehouse pickings, changing an order and the item maintenance also.

For this requirement I would almost definitely use production lots, because then it is real simple. OCA Modules already exist to put the lot on the SO Line.  e.g. https://github.com/OCA/sale-workflow/tree/13.0/sale_order_lot_selection

Your statement that lots are about traceability after stock operations is somewhat only partly correct. Of course the usual way is through a receipt or manufacturing operation, but I doubt you are taking sale orders for items that you 1. Don't know the condition of, 2. Don't have. But if so, then it is easy anyway, you can just create one.  In any case, it is at the point where you know the condition of the itme that you create the lot.

You then just need to add effectively a List Price field to lots and update the pricing rules of product.pricelist to use this price if lot is set. 

Anything else is just noise, you could add fields to lots like product attributes values if you chose, a text field for description, update the SO document to print extended info from that.

Easy.

Hello,

those odoo-pim modules look very useful to me. I need to use something similar 
to (product_)attribute_set but until now I was focused on base_custom_info/
product_custom_info. This seems very similar to these in my opinion. If 
anybody's familiar with both is there any significant difference that should be 
taken into account?

Side-questin: all the modules in 13.0 branch are marked as non-installable. 
Are they not ready yet?

Thank you for great effort. Really appreciated.

Best regards
