About Third-Party Product Availability Applications

Product availability information is stored in third-party ATP systems. When a salesperson clicks the Inquire button, or when a customer clicks a Check Availability button, the product availability information is passed to the Siebel Business Application by a third-party product availability fulfillment engine, also known as an availability-to-promise (ATP) engine. Siebel Order Management displays whatever data the ATP engine returns.

Integration with the product availability fulfillment engine uses the business service named External ATP Check. In addition it uses a specific, prebuilt Application Services Interface (ASI) named ATP Check. Some configuration is required to set up this integration.

Siebel Application Service Interface (ASI) is used to integrate order management with third-party product-availability applications. For an overview of how ASIs are used for integrating order management, see About ASIs for Order Management. For general information about how to set up, use, and modify integrations based on ASIs, see Integration Platform Technologies: Siebel Enterprise Application Integration.
