One of the keys to acting flexibly and quickly to customer expectations? Knowing the ‘available-to-promise’ quantity: the portion of your inventory and planned production that is ‘uncommitted’ and, consequently, available to promise to customers. aATP, the advanced ATP functionality in SAP S/4HANA, provides accurate and reliable order promise dates, taking into account the relevant supply and inventory in real time.
SAP landscape: aATP in SAP S/4HANA is the successor of gATP (Global ATP) which is part of APO. The difference?
- more functionalities, while maintaining an easier setup and maintenance
- fully embedded in S/4 and more user friendly, thanks to the Fiori interface
- no integration between systems is required
- faster performance, thanks to the HANA in-memory database.
Prioritise sales orders, look for alternatives and boost profitability
As order promising is complex, the aATP software provides a host of truly advanced features. More than checking product availability and providing order promise dates, it allows you to move away from the first-come-first-serve principle by helping you
- differentiate between your customers according to profitability, strategic importance or other factors, so you can prioritise sales orders for your most important customers or customer segments;
- cancel the open order of a lower-priority customer if a high-priority customer places an order and the stock is unavailable;
- allocate materials in short supply to, for example, specific regions and customers for a specific time period;
- define extra confirmation constraints (e.g., limited shipping capacity);
- run a mass recalculation of confirmations based on customisable priority rules;
- look for alternative supply in case of shortages, such as similar products or availability of the product in another plant or warehouse.
aATP: your benefits
- Reliable order promises based on real-time data
- Fast response time to orders
- Intuitive and fast reassignment of stocks
- Easy management of business priorities and profitability
- Inventory optimisation
- Improved customer service levels
