• Key Concepts: 
  Chained method call is a feature of the ABAP Runtime Environment (BC-ABA) that allows multiple methods to be called in a single statement. This allows for more efficient coding and better performance. It also allows for more complex logic to be implemented in a single statement. 
  
  How to use it: 
  To use chained method call, you must first define the methods that you want to call in the same statement. Then, you can use the syntax “METHOD1->METHOD2->METHOD3” to call all three methods in one statement. This syntax can be used for any number of methods, as long as they are all defined beforehand. 
  
  Tips & Tricks: 
  When using chained method calls, it is important to remember that the order of the methods matters. The order in which they are called will determine the output of the statement. Additionally, it is important to ensure that all of the methods are compatible with each other and that they will not cause any errors when used together.
