Prestashop Availability by Local Store

[medka]

I have a PrestaShop 1.6.1.10 online shop and 6 local stores. On the product page I want to show the availability of the product in every local store. I get the data form the ERP (Dynamics NAV) with a PHP script that loops through the ps_product to get the list of products and query the ERP to get the availability in the 6 local stores.

Now the big problem is that I didn't find where to put the quantity of any product in each local store.

Every thing works fine from getting the list of all products to getting the availability of each product in every local store.

Just give me where to put that information no need for how to write the queries I already know.

PS: I didn't post any code as for getting the information is already working and for inserting it I don't even know where to start.

Any suggestions?

Thanks
