• Key Concepts: 
  The Remote Function Call (RFC) interface is a communication protocol used by SAP systems to enable communication between different systems. It is part of the BC-ABA ABAP Runtime Environment component and allows for the exchange of data between different SAP systems, as well as between SAP systems and external applications. 
  
  How to use it: 
  The RFC interface can be used to transfer data from one system to another, or to access data from an external application. To use the RFC interface, you must first create a connection between the two systems. This can be done using the SAP GUI or by using a third-party tool such as SAPLink. Once the connection is established, you can then use the RFC interface to transfer data between the two systems. 
  
  Tips & Tricks: 
  When using the RFC interface, it is important to ensure that both systems are using compatible versions of SAP software. Additionally, it is important to ensure that both systems have the same user credentials in order for the connection to be successful.
