Learn about the key integration points between SAP Supply Chain Management (SCM) and SAP ERP Central Component (SAP ECC) required to effectively implement Global Available-To-Promise (Global ATP). Understand the configuration and master data elements that can influence this integration and learn about the potential impact of Global ATP on the order fulfillment processes.
Key Concept
When you are implementing Global Available-To-Promise (Global ATP), it is critical to have cross-functional teams appreciate the process and technical integration aspects early on in the project. Understanding these aspects can help set realistic expectations and avoid surprises during integration testing.

Implementing SAP Advanced Planning & Optimization (SAP APO) Global Available-To-Promise (Global ATP) can have a significant impact on the entire order fulfillment process cycle, including order entry, pricing, shipping, and billing. An understanding of the process and technical aspects of integration is crucial for an effective and smooth implementation.

In the first part of this series, we provided a high-level overview of Global ATP functionality and how it helps organizations improve their order fulfillment processes. In the second part we discuss integration aspects that take two forms — process and system. We discuss the business process impact of Global ATP in areas such as pricing and shipping as well as the technical configuration or master data required for integration. We provide information that helps project teams planning on implementing Global ATP with SAP ERP Central Component (SAP ECC) as the order entry and execution system.

We assume that the reader is reasonably familiar with basic SAP SCM and SAP ECC concepts. We focus on the Global ATP-specific integration aspects only. Other integration steps that are common across SAP SCM modules are not emphasized. The reader is advised to follow SAP configuration guides, online help documentation, and other SAPexperts articles wherever required.
We outline the following points:
  • Key configuration steps that should be taken into account in SAP ECC and SAP SCM and their interaction
  • Master data integration between SAP ECC and SAP SCM
  • Specific functionalities in SAP SCM (such as rules-based ATP) and what should be considered when implementing these functionalities
  • Customizing in SAP ECC and SAP SCM and leading practices for transporting customizing from system to system
  • Recommendations and points to consider for Global ATP check by document type (such as sales orders and stock transport orders)

The order of the concepts discussed in this article closely follows the order that you may want to consider in an actual implementation (although the concepts and topics that we cover should not be deemed a step-by-step cookbook).
