• Key Concepts: 
  Method chaining is a programming technique used in the ABAP Runtime Environment of SAP. It allows developers to chain multiple methods together in a single statement, making code more concise and efficient. This technique is especially useful when dealing with complex data structures or when multiple methods need to be called in succession. 
  
  How to use it: 
  Method chaining can be used in the ABAP Runtime Environment of SAP by first declaring a variable of type REF TO and then assigning it to an object. The variable can then be used to call multiple methods in succession, with each method returning a reference to the same object. This allows developers to chain multiple methods together in a single statement. 
  
  Tips & Tricks: 
  When using method chaining, it is important to remember that each method must return a reference to the same object. If a method returns a different object, the chain will be broken and an error will occur. Additionally, it is important to ensure that all methods are valid for the object being referenced.
