• What is the cause and solution for SAP error message CMMFDAI_FIX_MESSAGE018 - Illegal Dynamic call for Class & ?

  The SAP error message CMMFDAI_FIX_MESSAGE018 with the description "Illegal Dynamic call for Class &" typically occurs in the context of ABAP programming when there is an attempt to dynamically call a method or function of a class that is not allowed or does not exist. This can happen for several reasons, including:
  Causes:
  
  Incorrect Class Name: The class name being called dynamically may be misspelled or does not exist in the system.
  Method Not Found: The method being called on the class may not exist or is not accessible due to visibility (e.g., it may be private).
  Dynamic Call Restrictions: Certain classes or methods may have restrictions on dynamic calls, especially if they are not designed to be instantiated or called dynamically.
  Namespace Issues: If the class is in a different namespace and not properly referenced, it may lead to this error.
  Incorrect Parameters: The parameters being passed to the method may not match the expected signature, leading to a failure in the dynamic call.
  
  Solutions:
  
  Check Class and Method Names: Verify that the class name and method name are spelled correctly and that the class exists in the system.
  Access Modifiers: Ensure that the method you are trying to call is public or protected, and that it can be accessed from the context in which you are trying to call it.
  Review Dynamic Call Logic: If you are using dynamic calls (e.g., using CALL METHOD or CREATE OBJECT), ensure that the syntax is correct and that the class is designed to be instantiated or called dynamically.
  Parameter Validation: Check the parameters being passed to the method to ensure they match the expected types and number.
  Debugging: Use debugging tools to trace the execution and identify where the error occurs. This can help pinpoint the exact cause of the issue.
  Consult Documentation: Review the SAP documentation for the specific class and method to understand any restrictions or requirements for dynamic calls.
  
  Related Information:
  
  ABAP Documentation: Refer to the official SAP ABAP documentation for guidelines on dynamic calls and class/method definitions.
  SAP Notes: Check SAP Notes for any known issues or patches related to the specific class or method you are working with.
