To set up an Excluded SKU, log into GFS and select Inventory listed on the left sidebar. Next, select SKU Mapping on the inner left sidebar. There you may click on the 3 vertical dots next to Client SKUs in bold to Create Client SKU. When creating the new SKU, ensure the SKU Type is set to Excluded to create an Excluded SKU successfully.
Please note: Excluded SKUs will be ignored on orders, and any Shippable SKUs on the order will be processed for fulfillment.
