• Key Concepts: 
  Horizontal supply protection is a component of SAP's Available-to-Promise (ATP) module. It is used to ensure that the same material is not sold to multiple customers at the same time. This helps to prevent overbooking and ensures that customers receive their orders on time. 
  
  How to use it: 
  Horizontal supply protection can be enabled in the SAP system by setting up a check rule in the ATP configuration. This rule will check for any existing orders for the same material and prevent any new orders from being created if there is already an order for that material. 
  
  Tips & Tricks: 
  When setting up the horizontal supply protection check rule, it is important to consider the lead time of the material and any other factors that could affect the availability of the material. This will help to ensure that customers are not overbooked and that they receive their orders on time.
