Products per store: categories?

[heyciao]

Hi all,

need a help solving this issue:

(prestashop 1.4.6..) I create two stores in BO.

 

Now, in store A you find products A-group, in store B, B-groups products.

A and B can also be intersected.

 

Is there any field in the product table in which inserting id_store of the ps_store table?

 

I'm using prestashop catalogue mode, so when you choose a product you can save it into your whishlist and then joining the physical shop to buy it.

 

Should I use categories?

I'd like to have in the products BO a select field showing stores created before.

Does it exists?

 

How would you solved that?

Thank you.

Ciao
