• What is the cause and solution for SAP error message CNV_00001197 - Method &1 has no exporting parameter ?

  The SAP error message CNV_00001197 indicates that a method in a class does not have any exporting parameters defined. This error typically arises during the execution of a method call where the system expects to receive data through exporting parameters, but none are defined in the method signature.
  Cause:
  
  Method Definition: The method in question is defined without any exporting parameters. This could be due to an oversight during the method implementation.
  Incorrect Method Call: The method is being called with the expectation of receiving data back, but the method does not provide any exporting parameters to return that data.
  Code Changes: If the method was modified or refactored, it might have lost its exporting parameters unintentionally.
  
  Solution:
  
  
  Check Method Definition: Review the method definition in the ABAP class. Ensure that it has the appropriate exporting parameters defined if it is supposed to return data.
  
  You can do this by navigating to the class in the ABAP Workbench (SE80 or SE24) and checking the method signature.
  
  
  
  Modify Method Call: If the method is not supposed to have exporting parameters, ensure that the calling code does not attempt to use exporting parameters. Adjust the method call accordingly.
  
  For example, if the method is defined as:
  METHOD my_method.
  ENDMETHOD.
  Ensure that it is called without expecting any exporting parameters:
  CALL METHOD my_class=>my_method.
  
  
  
  
  Documentation and Comments: If the method is intended to be used without exporting parameters, consider adding comments or documentation to clarify its usage to prevent future confusion.
  
  
  Testing: After making changes, test the method to ensure it behaves as expected and that the error does not occur again.
  
  
  Related Information:
  
  ABAP Documentation: Familiarize yourself with the ABAP documentation regarding method definitions and parameter types (IMPORTING, EXPORTING, CHANGING, etc.).
  Debugging: Use the ABAP debugger to step through the code and observe where the error occurs. This can provide insights into the method call and its parameters.
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional context or fixes.
  
  By following these steps, you should be able to resolve the error CNV_00001197 effectively.
