• Key Concepts: 
  RAP type mapping is a feature of the BC-ESI-RAP RESTful ABAP Programming Model. It allows developers to map ABAP data types to JSON data types, allowing for easier integration between ABAP and JSON. This mapping is done using the RAP type mapping editor, which is part of the SAP Web IDE. 
  
  How to use it: 
  To use RAP type mapping, open the RAP type mapping editor in the SAP Web IDE. From there, you can select an ABAP data type and map it to a JSON data type. You can also create custom mappings if needed. Once you have finished mapping your data types, you can save your changes and use them in your application. 
  
  Tips & Tricks: 
  When creating mappings, it is important to consider how the data will be used in your application. For example, if you are using a date field, make sure to map it to a JSON date type so that it can be properly parsed by the application. Additionally, make sure to test your mappings before deploying them in production.
