  The SAP error message CX_WDK_CONTROLLER021 indicates that a script in the Web Dynpro ABAP application has exceeded the maximum allowed number of lines. This is a common issue when developing Web Dynpro applications, as there are limits on the size and complexity of scripts to ensure maintainability and performance.
  Cause:
  
  Excessive Script Length: The script you are trying to execute has too many lines of code. SAP has a limit on the number of lines in a single script to prevent performance issues and to encourage better coding practices.
  Complex Logic: If the script contains complex logic or multiple functionalities, it can easily exceed the line limit.
  Poor Code Structure: Not following best practices in code organization can lead to long scripts that are difficult to manage.
  
  Solution:
  
  
  Split the Script: Break down the long script into smaller, more manageable pieces. You can create multiple methods or functions to handle different parts of the logic.
  
  Modularization: Identify logical sections of the script and create separate methods for each section. This not only helps in reducing the line count but also improves code readability and maintainability.
  Use of Includes: If applicable, consider using include programs to separate parts of the code into different files.
  
  
  
  Refactor Code: Review the script for any redundant or repetitive code that can be simplified or removed. Refactoring can help reduce the overall line count.
  
  
  Use of Events: If the script is handling multiple events, consider separating the event handling logic into different methods or classes.
  
  
  Review Best Practices: Familiarize yourself with best practices for Web Dynpro ABAP development to ensure that your code is efficient and maintainable.
