Difference between "Fill SKU #x" and "SKU #x"

When selecting which sku to use on labels, what is the difference between the two?
I'm using Woocommerce and "sku# 1" and "sku #2" is working just fine. Just curious :)

    Hey @Robert@310C5 ,

    The FIllSKU is a field in the Product Defaults that we use for cases where the SKU that imports in does not match the SKU that your fulfillment service needs to use to ship the item. It is very common with FBA as they just assign a SKU to your products when you go through their approval process.

    In most cases, you are going to want to use the "SKU #1", "SKU #2", etc on the label if you are fulfilling the packages yourself.
