Can I defined SKU in this way:
let's say I got a lot of M&M chocolates products, all the same chocolates product, and they got different bar code. Can I say that the sku works like the bar code, it's unique for every products with different ID??
But I can't seem how SKU will helped on tracking products, should I export the whole product list?? I mean when I want to track a products, I just input the products title to search it, right? If I want to search the certain specific product, it means I need to have specific SKU to search it, it this the function of SKU??
