We have two different groups of customers. We are implementing SAP E-commerce 7.0 for ERP, B2B scenario. All these customers are US customers only, language is EN and currency is USD. Our requirement is to provide different ISA web applications to these groups of customers. We need to have different branding, different contact information, help pages, different product catalog etc. for these two web applications. Is it possible to achieve this functionality by creating two webshops? or do we need to create multiple web applications (and enterprise application)? Also, the users of one application shouldn't be able to access the other application or see any of its orders or products.
