Purpose

Increasingly, companies operating worldwide are forced to globalize available information in order to conduct business efficiently. Specifically, this means that information has to be made available across system boundaries as quickly as possible to provide optimized decision support. Global ATP can be used in heterogeneous system landscapes to provide required information as quickly as possible. Global ATP is one of the central methods of SAP Advanced Planning and Optimization (SAP APO)that utilizes SAP liveCache. The data is stored in the SAP liveCache in the form of ATP time series.

Global ATP contains the functions for the ATP check in SAP APO. Scheduling , which is performed in SAP APO, is also a part of this. The ATP check – also known as the availability check – represents an online search that should ensure that your company can provide the requested product at the requested time in the quantity requested by the customer. The ATP check can determine, using the so-called check methods , if a requirementcan be confirmed.

The check methods, which are also known to the ERP system, have been extended in SAP APO by the following new methods, such as:

In Capable-to-Promise (CTP) and the multilevel ATP check, Production Planning and Detailed Scheduling (PP/DS) is called to cover the requirement, while in the rules-based ATP check, substitutions can be checked to confirm the requirement. The correlation calculation corresponds to an enhanced function of Delivery Group Correlationin the ERP system.

You can use Backorder Processing to reset the confirmations from an ATP check and to reallocate them.

The Explanation and Simulation of the Availability Check allows you to display the check results and simulate the ATP check. You can also simulate Transportation and Shipment Scheduling there.

Integration

You can call Global ATP using different functions from SAP APO or components from an OLTP system. For more information, see Calling the ATP Check from Different Systems .
