Question
How does your integrator handle SKUs for product variations such as color, size, etc.?
Answer
Sounds like you are using Eagle's Style Color Size (SCS) Module. When you use SCS, Epicor Eagles sends us data for your product variants in a format similar to the following (partial list showing):
In this example you can see that MMADE1 and MMADE2 are the "parent" products with all the items underneath them being the "child" products (e.g. the variants of the product). The integration uses these fields to group and create the products in Bigcommerce, Magento, Shopify or WooCommerce.
