• Key Concepts: 
  Checking horizon is a feature of SAP's Global Available-to-Promise (ATP) component of the Supply Chain Management (SCM) module. It is used to determine the availability of a product for a certain period of time. The checking horizon is the maximum number of days that the system will look ahead to check for availability. 
  
  How to use it: 
  The checking horizon can be set in the ATP configuration settings. This setting determines how far ahead the system will look for available stock when calculating ATP. The default setting is usually 30 days, but this can be adjusted depending on the needs of the business. 
  
  Tips & Tricks: 
  It is important to set the checking horizon correctly, as it can have a significant impact on the accuracy of ATP calculations. If the checking horizon is set too low, then some available stock may not be taken into account when calculating ATP. On the other hand, if it is set too high, then it may lead to inaccurate calculations due to stock that may become available in the future.
