Store groups
The store group is used by all stores to share assets without having to create an asset store to hold them. For example, all TaxCategories, SupportedLanguages, SupportedCurrencies, CalculationCodes, and ShippingJurisdictions that are defined in the store group are automatically available for use by all stores.
On an HCL Commerce instance, a single store group is supported, and not multiple stores. To share assets among multiple stores, you can also use storepath and asset stores. You can create multiple asset stores to hold different assets.
