One of the biggest flaws of Odoo is the fact that when importing records it tries to match the name. In reality names can change but for other software you mostly use SKU for products.

Furthermore, Odoo expects that all data that comes in is being exported before.
Also here - in reality - you get lists from vendors and partners and import them maybe once or several times a year.

Does anyone know how to write a little module so I can import products matching on sku (default_code) or maybe rewrite the id so it matches the sku?
