• What is the cause and solution for SAP error message OO621 - The exception class & is derived from CX_NO_CHECK ?

  The SAP error message OO621 indicates that an exception class is derived from CX_NO_CHECK, which means that the exception is not intended to be caught or handled in the usual way. This is a specific type of exception in the ABAP programming language that is used to signal that an error has occurred, but it is not meant to be handled by the calling program.
  Cause:
  The primary cause of this error is that the program or function module is trying to catch an exception that is derived from CX_NO_CHECK. Since exceptions of this type are not meant to be caught, the ABAP runtime environment raises this error to indicate that the exception handling mechanism is being misused.
  Solution:
  To resolve this issue, you should:
  
  
  Review Exception Handling: Check the code where the exception is being caught. Ensure that you are not trying to catch exceptions that are derived from CX_NO_CHECK. Instead, you should allow these exceptions to propagate up the call stack.
  
  
  Modify Exception Handling Logic: If you need to handle specific errors, ensure that you are only catching exceptions that are not derived from CX_NO_CHECK. You can do this by checking the documentation of the exception classes you are working with.
  
  
  Refactor Code: If your logic requires handling certain conditions, consider refactoring your code to avoid catching these exceptions. You may need to redesign the flow of your program to accommodate this.
  
  
  Consult Documentation: Review the SAP documentation for the specific exception class you are dealing with. Understanding the purpose and intended use of the exception can help you determine the best way to handle errors in your application.
  
  
  Related Information:
  
  CX_NO_CHECK: This is a base class for exceptions that are not meant to be caught. It is typically used for serious errors that indicate a failure in the program logic or an unrecoverable state.
  Exception Handling in ABAP: Familiarize yourself with the exception handling mechanisms in ABAP, including the use of TRY...ENDTRY blocks and the different types of exceptions.
  Debugging: Use the ABAP debugger to trace the execution of your program and identify where the exception is being raised. This can provide insights into why the exception is occurring and how to address it.
  
  By following these steps, you should be able to resolve the OO621 error and improve the robustness of your ABAP code.
