• What is the cause and solution for SAP error message FUNC_ADT014 - Function modules can not contain old and class-based exceptions ?

  The SAP error message FUNC_ADT014 indicates that there is an issue with the way exceptions are defined in a function module. Specifically, it states that function modules cannot contain both old-style exceptions (which are defined using the EXCEPTIONS keyword) and class-based exceptions (which are defined using the TRY...CATCH construct with exception classes).
  Cause:
  The error occurs when a function module is defined with a mix of old-style exceptions and class-based exceptions. This is not allowed in SAP ABAP, as it can lead to ambiguity in exception handling. The system expects a consistent approach to exception handling within a function module.
  Solution:
  To resolve this error, you need to choose one method of exception handling for your function module. Here are the steps you can take:
  
  
  Remove Old-Style Exceptions: If you want to use class-based exceptions, remove the EXCEPTIONS section from your function module definition. Instead, use TRY...CATCH blocks to handle exceptions.
  Example:
  FUNCTION my_function.
    TRY.
      " Your code here
    CATCH cx_my_exception INTO DATA(lx_my_exception).
      " Handle the exception
    ENDTRY.
  ENDFUNCTION.
  
  
  Use Old-Style Exceptions: If you prefer to keep using old-style exceptions, remove any class-based exception handling from your function module. Define your exceptions using the EXCEPTIONS keyword.
  Example:
  FUNCTION my_function.
    " Your code here
  EXCEPTIONS
    my_exception = 1
    others = 2.
  ENDFUNCTION.
  
  
  Consistency: Ensure that all parts of your function module are consistent with the chosen exception handling method. This includes any calls to the function module from other programs or function modules.
  
  
  Related Information:
  
  Old-style exceptions: These are defined in the function module interface using the EXCEPTIONS keyword. They are typically represented as numeric return codes.
  Class-based exceptions: These are defined using ABAP classes and are more flexible and powerful. They allow for more structured error handling and can carry additional information about the error.
  Best Practices: It is generally recommended to use class-based exceptions in new developments, as they provide better error handling capabilities and are more aligned with modern ABAP programming practices.
  
  By following these guidelines, you should be able to resolve the FUNC_ADT014 error and ensure that your function module is correctly defined.
