• Key Concepts: 
  Substitution item type is a feature of the SAP Available-to-Promise (ATP) component. It allows users to substitute one item for another in order to fulfill an order. For example, if a customer orders a product that is out of stock, the substitution item type feature can be used to substitute a similar product in order to fulfill the order. 
  
  How to use it: 
  In order to use the substitution item type feature, users must first define the substitution item type in the SAP system. This is done by creating a substitution rule that defines which items can be substituted for each other. Once the substitution rule is created, users can then select the substitution item type when creating an order. 
  
  Tips & Tricks: 
  When creating a substitution rule, it is important to consider the customer’s needs and preferences. For example, if a customer orders a specific product, it may not be possible to substitute a different product without compromising on quality or features. Therefore, it is important to consider the customer’s needs when creating a substitution rule.
