  typically occurs in the context of Web Dynpro ABAP applications. Here's a detailed explanation of the cause, solution, and related information:
  
  Cause
  
  The error WD079 Exception '& not raised' indicates that an expected exception was not raised during the execution of a Web Dynpro component or method.
  In Web Dynpro ABAP, certain methods or operations are designed to raise exceptions under specific conditions. If the code or framework expects an exception to be raised but it does not happen, this error is triggered.
  The placeholder & in the message is usually replaced by the name of the exception class or exception ID that was expected.
  This can happen due to:
  
  Incorrect exception handling in the Web Dynpro component.
  A mismatch between the expected and actual behavior of the method.
  Programming errors where the exception is not raised as intended.
  Framework or runtime inconsistencies.
  
  
  
  
  Solution
  
  
  Check the Exception Handling in the Code:
  
  Review the Web Dynpro component or method where the exception is expected.
  Verify that the exception is properly raised using RAISE EXCEPTION or the appropriate syntax.

  Review the Web Dynpro Component Configuration:
  
  Sometimes, the error can be caused by incorrect configuration or missing exception declarations in the component interface or method signature.
  Make sure the exceptions are declared properly in the method interface.
