How Advanced ATP in SAP S/4HANA Mitigates Order Processing Challenges in SAP APO

Available-to-promise (ATP) is an order promising process that refers to the amount of inventory that is in stock to confirm an order.


SAP’s new solution for this is called SAP S/4HANA for advanced ATP (advanced ATP), which is the successor solution to global ATP in SAP Advanced Planning and Optimization (SAP APO). In this post, we’ll discuss how advanced ATP in SAP S/4HANA helps mitigate order processing challenges. First, let’s explore the challenges of order processing.


Order Processing Challenges

Order processing is when a company commits to its customer orders with reliable delivery schedules based on the availability of requested products. An efficient order promising strategy helps companies be resilient when facing supply chain disruptions and stay profitable considering all sales and delivery constraints.

Some of the typical challenges in the order promising process include confirming orders in real time, adhering to the promised timeline, keeping the customer informed, responding to changes, managing multiple distribution channels, dealing with supply chain restraints, and integrating between fulfillment units. 

When it comes to SAP APO, there are a handful of challenges that prompted SAP to develop advanced ATP. SAP APO is a standalone solution, so it needs to be deployed outside of SAP ERP, and the data must be replicated and integrated via the core interface (CIF). Even if the CIF provides near real-time integration, inconsistencies could still arise due to unexpected integration errors. Also, global ATP still uses the old technology of SAP liveCache, and even if SAP APO could be deployed over SAP HANA, it wouldn’t benefit from the technology and utilities of SAP HANA. Now, let’s take a look at how SAP’s new approach to ATP solves these issues. 


To address the limitations of SAP APO, SAP built advanced ATP into the SAP S/4HANA enterprise solution. The major focuses when developing the solution were a simplified architecture, faster response time, flexible deployment options, intuitive and user-friendly interfaces, new and enhanced functionalities, and integration to other modules.  

Advanced ATP provides accurate and reliable order promise dates that consider the relevant supplies across the network and critical supply chain constraints in real time, such as inventory positioning, transportation, production, and procurement. At the same time, it also helps protect companies’ business priorities and profitability goals. Companies can mass-process orders in high volume, catering to customer priorities and changing supply situations with intuitive requirement classification and automated exception handling.

Often times, companies experience inventory shortage situations. Advanced ATP helps manage this by maintaining sales constraints in product allocation (PAL) while improving customer service levels by confirming orders based on delivery constraints.

Other capabilities of advanced ATP include:

  • Establish fixed links between supply and demand elements until final delivery to avoid reassignment of dedicated supplies to competing demands
  • Intelligently select alternative locations and/or substitutable products during stock outage in the requested delivery plant
  • Protect quantities of a material in a specific plant for key customers and businesses against other competing demands
  • Confirm orders based on real-time production and scheduling constraints when the requested finished product isn’t available in the full quantity
  • Use the Review Availability Check Result app to get a comprehensive understanding of why an order is confirmed the way it is
  • Reassign stock manually with impact analysis before release for delivery

ATP is an integral part of the order fulfillment process. It’s a vital tool when there are supply shortages and customers demand assured commitments. SAP’s new functionalities in SAP S/4HANA make it possible for companies to streamline this process and improve overall customer satisfaction.
