• Key Concepts: 
  A virtual field is a feature of the BC-ESI-RAP RESTful ABAP Programming Model that allows developers to create a field in an ABAP program that does not exist in the database. This field can be used to store data that is not stored in the database, such as calculated values or values from external sources. 
  
  How to use it: 
  Virtual fields can be used in ABAP programs to store data that is not stored in the database. To create a virtual field, the developer must define the field in the ABAP program and specify its type and length. The virtual field can then be used like any other field in the program. 
  
  Tips & Tricks: 
  When creating a virtual field, it is important to ensure that the type and length of the field are correct. This will ensure that the data stored in the virtual field is valid and can be used correctly.
