What is correlation calculation mode in SAP SCM-APO-ATP - Global Available-to-Promise?

SAP Term: correlation calculation mode

• Component: SCM-APO-ATP

• Component Name: Global Available-to-Promise

• Description: Setting that defines how the requirement quantity of a component is to be confirmed. The system normally attempts to confirm the total requirement quantity of a component if the ATP quantity allows this. If all components have been checked, a correlation calculation is then carried out that determines the total confirmation. If a correlation without adjustment is made, the confirmed quantities of the components are not changed. If a correlation with adjustment is made, the confirmed quantities of the components are adjusted based on the components with the least confirmation.

• Key Concepts: 
  Correlation calculation mode is a feature of the Global Available-to-Promise (ATP) component of SAP's Supply Chain Management (SCM) module. It is used to determine the availability of a product for a customer order. The correlation calculation mode determines how the ATP system will calculate the availability of a product based on the customer's order requirements. 
  
  How to use it: 
  The correlation calculation mode can be set in the ATP configuration settings. Depending on the setting, the ATP system will either calculate availability based on the customer's order requirements or based on the product's availability in stock. The correlation calculation mode can also be used to determine whether or not a product is available for a customer order. 
  
  Tips & Tricks: 
  When setting up the correlation calculation mode, it is important to consider how it will affect the accuracy of the ATP system's calculations. If the correlation calculation mode is set too low, then it may not accurately reflect the availability of a product for a customer order. On the other hand, if it is set too high, then it may lead to inaccurate calculations and incorrect availability information. 
  
  Related Information: 
  The correlation calculation mode is closely related to other features of SAP's SCM-APO-ATP module, such as demand forecasting and inventory optimization. It is important to understand how these features interact with each other in order to ensure that the ATP system is accurately calculating availability for customer orders.
