Why Export a Catalog?
Exporting catalogs lets you make them available for other Commerce Server 2009 sites or trading partners. You might want to export a catalog if, for example, you are selling products wholesale and you want to export your catalogs to retailers. Alternatively, you might want to export a catalog to another application, for example, an inventory system or a pricing system.
You export the catalog data to a location on a server computer or a network share that the server computer can access. You use the Catalog Manager to export catalog data from an existing catalog in XML format. You select the language in which you want to export the catalog data or you can export the catalog data in all languages. You can perform a full catalog export, an expression-based export, or an incremental export of the catalog from a specified start date. For example, you can export only your most recent changes instead of importing the whole catalog.
