  Key Concepts: 
  Predicate functions are a type of function module in the ABAP Runtime Environment of SAP. They are used to evaluate a condition and return a Boolean value (true or false). Predicate functions are used to determine whether a certain condition is met, and can be used in various scenarios such as loop control, decision making, and data validation. 
  
  How to use it: 
  Predicate functions can be used in various scenarios such as loop control, decision making, and data validation. To use a predicate function, you must first define the function module in the ABAP Runtime Environment. Then, you can call the function module from your program code and pass in the necessary parameters. The function will then evaluate the condition and return a Boolean value (true or false). 
  
  Tips & Tricks: 
  When using predicate functions, it is important to ensure that the parameters passed into the function are valid. This will ensure that the function returns an accurate result. Additionally, it is important to consider the performance implications of using predicate functions as they can be computationally expensive.
