• Key Concepts: 
  Predicate method call is a feature of the ABAP Runtime Environment (BC-ABA) that allows for the execution of a method based on a condition. This condition is known as a predicate, and it is used to determine whether or not the method should be executed. The predicate can be any valid ABAP expression, such as a comparison between two values or a check for the existence of an object. 
  
  How to use it: 
  To use the predicate method call feature, you must first define the predicate in the ABAP code. This can be done by using the IF statement and specifying the condition that must be met for the method to be executed. Once the predicate has been defined, you can then call the method using the CALL METHOD statement. The CALL METHOD statement will execute the method if and only if the predicate evaluates to true. 
  
  Tips & Tricks: 
  When using predicate method calls, it is important to ensure that your predicates are well-defined and accurate. This will help to ensure that your methods are only executed when they should be, and not when they shouldn't. Additionally, it is important to remember that predicates can only evaluate to true or false; they cannot return any other values.
