• Key Concepts: 
  Validation is a process in the BC-ESI-RAP RESTful ABAP Programming Model that checks the correctness of data before it is stored in the database. It ensures that the data is valid and meets certain criteria, such as being within a certain range or having a specific format.
  
  How to use it: 
  Validation can be used to check the correctness of data before it is stored in the database. This can be done by setting up validation rules in the ABAP code. These rules can be used to check for specific criteria, such as whether a value is within a certain range or has a specific format. The validation process will then check the data against these rules and reject any data that does not meet them.
  
  Tips & Tricks: 
  When setting up validation rules, it is important to ensure that they are comprehensive enough to catch any potential errors. It is also important to ensure that the rules are not too restrictive, as this could lead to valid data being rejected. Additionally, it is important to provide meaningful error messages when validation fails, so that users can easily understand why their data was rejected.
