This allows you to analyze performance separately for each storefront. To set up storefront mapping, contact the commercial team with your storefront information. We'll configure the mapping to assign country-level data to your storefronts. See [Storefront assignment](/integrations/datawarehouse/fileTransfer#storefront-assignment) for details.
