In the tab “Item” you can enter the item condition as well as the product identification such as SKU, EAN, ISBN or UPC. It is also possible to enter an EPID (ebay´s Catalog Id) to link an item to the catalog. You can use the button “Catalog search” (see catalog description) to search for products in the catalog. You can also determine the item location. If your location usually always remains the same, you can predefine it in the settings. It will then be set automatically when you create a new item.
