Availability & promising in customer journey
Introduction
The customer journey in the web shop typically involves various steps, from searching for an item on an overview page to completing an order on the checkout page. Each step requires a different level of detail on the "available to promise" (ATP) information. In general, the responses of the ATP calls get more and more specific the further the user proceeds in the checkout journey.
