In our current system (CE 10) we have imported 10 000 products through the import excel function of Odoo. But as we realize now there is more info needed in the product card than our initial import. Info like Vendors and prices of those vendors (in the inventory tab of the product template). Basically it needs a second import where we could only import that part of the product card (without overwriting or creating new articles). It's basically an add function where the new import fills those empty fields of the already existing products...
I've tried several ways but Odoo always creates new articles or overwrites old ones with other info, even with the external IDs respected.
What would be the best way to do this with such a massive database without messing it up??
Thanks
