Learn when and how to use Configurable Process Scheduling (CPS) in SAP Advanced Planning & Optimization (SAP APO) Global Available-to-Promise (Global ATP). Understand the master data needed to support CPS and help avoid common mistakes while setting up CPS.
Key Concept
Available-to-Promise (ATP) is an order management business process that attempts to commit to the customer-requested order quantities and dates based on availability of finished products, components, and resources. Transportation and shipment scheduling is a necessary part of the ATP check. If the ATP check is performed in SAP ERP Central Component (SAP ECC) this scheduling is based on logistics configuration objects such as shipping points and routes. However, if the ATP check is performed in Global Available-to-Promise (Global ATP), it is necessary to use the scheduling functionality of SAP SCM.

Transportation and shipment scheduling involves backward scheduling to determine the requested material availability date based on the customer requested delivery date and then forward scheduling to determine the committed delivery date based on the committed material availability date. If the Available-to-Promise (ATP) check is performed in SAP ERP Central Component (SAP ECC), this scheduling is based on logistics configuration — shipping points or routes. However, if the ATP check is performed in SAP Advanced Planning & Optimization (SAP APO) Global Available-to-Promise (Global ATP) it is not possible to carry out the transportation and shipment scheduling in SAP ECC. You must then use one of the several options that are available in SAP SCM to perform transportation and shipment scheduling. One of these options is Configurable Process Scheduling (CPS). While it is the most flexible approach, it is also the most complex and probably the least documented method.

In this article, we aim to fill the gap in the documentation of CPS. We outline how transportation and shipment scheduling for sales orders and stock transport orders can be enabled using CPS in the context of an ATP check using Global ATP. Specifically, we will discuss the business requirements and configuration steps.

Note
There are a significant number of configuration steps required to implement GATP that are beyond the scope of this article. The reader is advised to follow SAP Configuration Guides as well as SAP’s online documentation wherever required.
