  Key Concepts: 
  A persistent field is a field in the SAP system that stores data for a longer period of time. It is part of the BC-ESI-RAP RESTful ABAP Programming Model, which is a programming model that allows developers to create applications that can access and manipulate data stored in the SAP system. 
  
  How to use it: 
  Persistent fields are used to store data that needs to be accessed and manipulated over a longer period of time. They are typically used for data that needs to be accessed by multiple applications or users. To use persistent fields, developers must first define them in the ABAP programming language. Once defined, they can be used to store and retrieve data from the SAP system. 
  
  Tips & Tricks: 
  When defining persistent fields, it is important to consider the type of data that will be stored in them. Different types of data require different types of fields, so it is important to choose the right type for the data being stored. Additionally, it is important to consider how often the data will need to be accessed and manipulated, as this will determine how often the persistent field needs to be updated.
