Yes i have tested Multi inventory. I will try to explain 🙂
Product 1 - We have in stock (qty 2)
Product 1 we can buy from 2 different suppliers.
Supplier 1 - have this in stock (qty 3)
Supplier 2 - Have in stock (qty 1)
We want to show on web total qty, and in this case qty = 6.
This is no problem to do as i can see in ATUM if we add inventory for each supplier and connect it to that supplier.
The problem is that in our system we have about 14000 products. If we want to do this we have to manually add inventory to each product. We want to automate this. With other word if this product(SKU) exist in price file we import, automatically assign the supplier with inventory to this product.
