• Key Concepts: 
  The RAP transactional buffer is a component of the BC-ESI-RAP RESTful ABAP Programming Model. It is a buffer that stores data temporarily during a transaction. This buffer is used to ensure that data is not lost during the transaction and that the data is consistent across all systems. 
  
  How to use it: 
  The RAP transactional buffer is used to store data temporarily during a transaction. This data can be accessed by other systems in the same transaction, ensuring that the data is consistent across all systems. The buffer can also be used to store data for later use, such as when a transaction needs to be rolled back or when data needs to be retrieved from another system. 
  
  Tips & Tricks: 
  When using the RAP transactional buffer, it is important to ensure that the data stored in the buffer is consistent across all systems. This can be done by using locks and transactions to ensure that only one system can access the data at any given time. Additionally, it is important to ensure that the data stored in the buffer is valid and up-to-date.
