Why Import a Catalog?
If you work with trading partners, you may need to import catalogs. You many also need to import catalogs if the catalogs were created on a different computer system and you want to import them onto your system. You can import catalogs on a "when needed" basis, or you can import catalogs on a regular schedule. You import catalogs in XML format.
There are two types of import that you can perform:
Incremental. If the catalog you are importing already exists in the Catalog System, Commerce Server 2009 updates the existing catalog data. If the catalog does not exist, Commerce Server 2009 creates a new catalog.
Replace. If the catalog you are importing already exists in the Catalog System, Commerce Server 2009 deletes the existing catalog and replaces it with a new catalog. If the catalog does not exist, Commerce Server 2009 creates a new catalog.
