A customer has to be stored for the login at the WEB SHOP Demo. A contact person, an email address and a password are stored in this customer entry. Both are done in SAP B1 > Business Partners > Business Partner Master Data > Contact Person.
It is possible to filter products with a specific property number checked to be displayed in the product list that you can add to the cart or configure. In this way, you can control which products appear in the web and hide all others not available to be shown to the customers. Beas 2020.08
