• Key Concepts: 
  Public Service Definition API is a component of the SAP Enterprise Service Infrastructure (BC-ESI). It provides a way to define and manage public services, which are services that are exposed to external systems. It also provides a way to define and manage service operations, which are the individual operations that make up a public service. 
  
  How to use it: 
  The Public Service Definition API can be used to create and manage public services and service operations. It can be used to define the parameters of a service operation, such as its input and output parameters, as well as its security settings. It can also be used to define the relationships between different service operations, such as which operations must be called in order for a particular operation to be executed. 
  
  Tips & Tricks: 
  When creating public services and service operations, it is important to ensure that they are properly secured. This means that only authorized users should be able to access the services and operations. Additionally, it is important to ensure that the parameters of each operation are properly defined so that they can be used correctly by external systems.
