Business Scenario
Your company uses SAP Internet Sales to sell configurable products over the Internet. Your customers visit your Web site, view and select product options, see how much it all costs, and trigger a sales order. You then upload order information to your SAP System. When your customers select a configurable product, the configuration and pricing are done by the Internet Pricing and Configurator.
Process Flow
All the R/3 data that the Internet Pricing and Configurator requires to configure products is downloaded to the CRM consolidated database.
This opens a subscreen, where the customer selects the product options she/he requires.

This subscreen is SAP Internet Sales' interface to the Internet Pricing and Configurator, which incorporates the SCE.
