• Key Concepts: 
  Additional save is a feature of the BC-ESI-RAP RESTful ABAP Programming Model that allows users to save data to the database without having to write a separate save statement. This feature is especially useful when dealing with large amounts of data, as it allows users to save all of the data in one go. 
  
  How to use it: 
  To use the additional save feature, users must first create an entity set in their ABAP program. This entity set will contain all of the data that needs to be saved. Once the entity set is created, users can then call the additional save method on the entity set. This will cause all of the data in the entity set to be saved to the database. 
  
  Tips & Tricks: 
  When using the additional save feature, it is important to ensure that all of the data in the entity set is valid before calling the additional save method. This will help prevent any errors from occurring when saving the data. Additionally, it is also important to ensure that all of the necessary fields are included in the entity set before calling the additional save method.
