• Key Concepts: 
  RAP external numbering is a feature of the BC-ESI-RAP RESTful ABAP Programming Model. It allows developers to assign an external number to an entity in the system, such as a customer or a product. This external number can then be used to identify the entity in other systems, such as an ERP system. 
  
  How to use it: 
  To use RAP external numbering, developers must first create an external number field in the system. This field can be used to store the external number assigned to the entity. Once the field is created, developers can assign an external number to an entity by setting the value of the field. 
  
  Tips & Tricks: 
  When assigning an external number to an entity, it is important to ensure that the number is unique and not already assigned to another entity. This will help prevent errors when referencing the entity in other systems.
