Here is a scenario:
1 may 2014: I bought 10 iPads from supplier Harry with Purchase Order Number: PO/001
1 may 2015: I bought 20 iPads from supplier Jacky with Purchase Order Number: PO/002
So I have 30 iPads in stock.
20 may 2015: I sell 15 iPads to customer Tom with Sales Order Number: SO/001
First question: Which iPads are taken from stock?
a) Can I select 10 iPads from PO/001 and 5 iPads from PO/002?
b) Does Odoo pick randomly like 15 iPads from PO/002 instead of using the iPads of PO/001?
20 may 2016: Customer Tom is not happy, one of his iPads is broken. The guaranteed warranty period is 2 years so he expects a free fix or replacement of the product.
Second question: Can the iPad be identified from which supplier or purchase order he was bought?
In case the iPad was bought from supplier Harry, the vendor warranty period of 2 years is already expired.
