This error indicates that an exception that is being raised in a method is not defined in the method's interface for the specified object type.
  Cause:
  
  Undefined Exception: The exception being raised in the method is not declared in the method's signature. In ABAP, when you define a method, you can specify which exceptions it can raise. If you try to raise an exception that is not listed, you will encounter this error.
  Typographical Error: There might be a typo in the exception name when raising it.

  Solution:
  
  Check Method Definition: Review the method definition in the class to ensure that the exception you are trying to raise is declared in the method's interface. You can do this by checking the RAISE clause in the method signature.
  METHOD your_method_name
    RAISES your_exception_name.
  
  Add Exception to Method: If the exception is not defined, you need to add it to the method's signature. Modify the method definition to include the exception.
  Correct Exception Name: Ensure that the name of the exception you are raising matches exactly with the name defined in the method signature. Check for any spelling mistakes or case sensitivity issues.
  Review Calling Code: If the method is being called from another location, ensure that the correct method is being invoked and that the calling code is prepared to handle the exceptions that the method can raise.
  
  Related Information:
  
  ABAP Documentation: Refer to the official SAP documentation for Object-Oriented ABAP programming to understand how exceptions are handled.
  Debugging: Use the ABAP debugger to step through the code and identify where the exception is being raised and whether it is defined in the method signature.
  SAP Community: Check forums and community discussions for similar issues, as other developers may have encountered and resolved the same error.
