Recall in 2015, SAP announced that Available to Promise capabilities would be built from the ground up in the core S/4HANA solution. At the time, the rationale for this strategic decision was to build next generation order promising functionality that would be simple to use and implement, while leveraging the central S/4HANA digital core platform. Now that aATP is becoming very real on the 1809 platform, we have hands-on config/modeling experience exploring cool new features like Segmentation while also providing tangible detailed comparisons to what is already available on the fully capable legacy global ATP platform.
One of the key obstacles for this approach would be that SAP customers, especially those already using APO’s global ATP (gATP), would have to wait for the promise and roadmap availability of key functionality offered in a brand new order promising engine within S/4HANA. Some of these current roadmap gap items include: Multi-Level (component) ATP, Product Substitution, and Capable to Promise
