This can happen in various scenarios, such as when working with ABAP programs, Web Dynpro applications, or other SAP components that utilize classes.
  Cause:
  
  Non-existent Class: The specified class (denoted by &1) does not exist in the SAP system.
  Incorrect Class Name: There may be a typo or incorrect naming convention used when referencing the class.

  Solution:
  
  
  Check Class Existence:
  
  Use transaction code SE24 (Class Builder) to check if the class exists. Enter the class name and see if it is available.
