For a product to have inventory, it must have a warehouse assigned to it in Optimizely <<product-name>>. A warehouse can be either a physical or logical segregation of inventory. Warehouses are usually assigned to products in the ERP integration; however, these directions demonstrate how to assign a warehouse to a product manually in case the need ever arises:
Within the Admin Console, go to **Catalog** \> **Products.**
Click **Edit** for the product to which you would like to assign a warehouse.
Select the **Warehouses** tab.
Click **Add Product Warehouse**.
Select the appropriate warehouse to assign to the product.
Click **Save** on the **Secondary Header.**
