A SKU group allows you to define the global markets, trading patterns, and their functionality. For more information, see [Grouping SKUs](https://docs.digitalriver.com/digital-river-api/product-management/setting-up-sku-groups). To configure your SKU groups, contact your Digital River Account Manager.

When updating the `skuGroupId`, it is important to update or change the Basic Product details simultaneously. This ensures that the product details are properly synchronized with Digital River when the webhook is triggered.
