Im looking for a way to give a product 2 diffrent SKU
And when customer continue to Checkout, the right SKU will be choosen depends on the Shipping country..
Is it possible?
Product SKU is the unique identifier for products. You can't (out-of-the-box) assign 2 SKUs.
Maybe you can use dynamic SKU (using custom options) to add some code after the original SKU but it depends on your implementation and business logic.
