Re: MRP BoM "upgrade products" - negative BoM line quantity

Hi Tom,


Maybe they should revise their procedures and assumptions?


Let us say the "upgrade kit" actually contains a negative quantity for one product, the machine that should be returned. Next you will have a Delivery Order (Stock Picking) with a negative quantity, meaning that you should receive something instead of sending something.....


Apart from throwing overboard some database consistency and reliability there are bound to be more problems further on.


Maybe look into the possibilities of the RMA modules where you can replace parts (or whole machines), and deal with financial consequenses?


Kind regards, Ronald

Hi Ronald,

It's not a correction of the order, but it's like selection an "option". So it's the same kit, but with another upgraded machine on top. This is how orders are done in their world, it seems.

Hi,


Maybe I am missing something. But if a customer ordered a wrong product, kit or not, why not just credit the sales order and create a new one for the right ACME 2000 XL kit?


Negative amounts in a BoM seems to me a recipe for disaster.


Kind regards, Ronald

Hi all

I have the following use case:

- Our client sells products as a "Kit", eg. "ACME 1000 kit". This is a 
product in Odoo with BoM of the actual "ACME 1000" device, together with 
some supporting items eg. ACME kit installation manual, ACME kit spare 
parts, ACME kit installation at customer site. On fulfilment of the sale 
order all these products are sent out together.

- Their client calls and doesnt want the ACME 1000, but the ACME 2000 
XL, but with the same supporting items. They order as a purchase order 
with two lines: "ACME 1000 kit", "Upgrade to ACME 2000 XL".

Now that second product "Upgrade to ACME 2000 XL" should contain a BoM 
of "+1 ACME 2000 XL, -1 ACME 1000", so that the net result is that the 
kit is the same, but with one machine swapped for the upgraded one. 
However I cannot define negative amount on a BoM line.

Does anyone know of a way / a module that is able to configure this?

Tom

PS. They want it this way so that the sale order lines and invoice lines 
match the customer's purchase order.
