need to locate file where macro 'PRODUCT_CODE' is defined

Hi,

If you mean that you want to change the way the product_code is generated by HikaShop when you don't provide it in the interface when creating a new product, then you want to edit the function "save" of the file administrator/components/com_hikashop/classes/product.php

I would however recommend to develop a small plugin of the group "hikashop" and implement the onBeforeProductCreate trigger and change the product_code with the one you want instead. That way, when you update, you won't loose your changes
