Walmart Integration
You can select an appropriate source of SKU value for your Walmart Items.

If Item SKU already exists in your Walmart inventory, you can enable the SKU modification option.
Please select a way of SKU modification:
Prefix - specified value will be added at the beginning of the initial SKU value.
**Postfix -**specified value will be added at the end of the initial SKU value.
Template - a new SKU value will be generated based on the entered pattern. For example, if the initial product SKU is 123 and your modification template is %value%-567, Walmart Item SKU will be 123-567.

M2E Pro can generate a random SKU value for your Channel Item if you enable Generate option.

Specify the Product Identifier (UPC, EAN, GTIN, ISBN) you want to assign to the products or use the Product ID Override option.

In case your products do not have Product Identifiers (e.g., hand-made products), you can use Product ID exemption.
