• What is the cause and solution for SAP error message ABAP_TESTDOUBLE031 - &4 Old and class-based exceptions cannot be used at the same time ?

  The SAP error message ABAP_TESTDOUBLE031 indicates that there is a conflict between the use of old-style exceptions (using RAISE and CATCH statements) and class-based exceptions (using TRY and CATCH blocks) in your ABAP code. This error typically arises when you attempt to mix these two exception handling mechanisms within the same method or program.
  Cause:
  
  Mixing Exception Handling Styles: The error occurs when you have a method or function that uses both old-style exceptions and class-based exceptions. For example, if you have a RAISE statement for an old-style exception and also use a TRY...ENDTRY block for class-based exceptions in the same context, this will trigger the error.
  Inconsistent Exception Declaration: If a method is declared to throw class-based exceptions but also contains old-style exception handling, it can lead to this error.
  
  Solution:
  To resolve this error, you need to ensure that you are consistently using one style of exception handling throughout your code. Here are the steps you can take:
  
  
  Choose One Exception Handling Style:
  
  If you want to use class-based exceptions, ensure that all exceptions are defined as class-based exceptions and use TRY...CATCH blocks for handling them.
  If you prefer old-style exceptions, remove any class-based exception handling and use RAISE and CATCH statements.
  
  
  
  Refactor Your Code:
  
  If you have mixed styles, refactor your code to eliminate the mixing. For example, if you have a method that raises an old-style exception, change it to raise a class-based exception instead.
  Ensure that all exception classes are properly defined and that you are catching the correct exceptions in your CATCH blocks.
  
  
  
  Check Method Signatures:
  
  Review the method signatures to ensure that they are consistent with the exception handling style you have chosen. If a method is declared to throw class-based exceptions, it should not contain any old-style exception handling.
  
  
  
  Related Information:
  
  Old-style Exceptions: These are the traditional way of handling exceptions in ABAP, using RAISE to trigger an exception and CATCH to handle it.
  Class-based Exceptions: Introduced in newer versions of ABAP, these exceptions are defined as classes and provide a more structured way to handle errors. They use TRY...CATCH blocks for handling exceptions.
  Documentation: Refer to the official SAP documentation on exception handling in ABAP for more details on how to implement both styles correctly.
  
  By following these guidelines, you should be able to resolve the ABAP error message ABAP_TESTDOUBLE031 and ensure that your exception handling is consistent and error-free.
