• What is the cause and solution for SAP error message /IWFND/CM_IFL023 - Application coding does not support actions ?

  The SAP error message /IWFND/CM_IFL023 Application coding does not support actions typically occurs in the context of SAP Gateway and OData services when an action is invoked that is not properly implemented or supported in the backend application logic.
  Cause:
  
  Missing Implementation: The action you are trying to call is not implemented in the backend service. This could be due to a missing method in the service class or the action not being defined in the OData service.
  Incorrect Service Definition: The OData service may not have the action defined in its metadata, or the action might not be correctly mapped to the corresponding backend logic.
  Authorization Issues: Sometimes, the action might be implemented, but the user does not have the necessary authorizations to execute it.
  Service Activation: The OData service might not be activated or properly registered in the SAP Gateway.
  
  Solution:
  
  
  Check Implementation: Verify that the action is implemented in the backend service. You can do this by checking the service class in the ABAP backend.
  
  Go to transaction SE80, select the relevant OData service, and check the associated class for the action method.
  
  
  
  Review Service Metadata: Ensure that the action is defined in the service's metadata. You can check this by accessing the service's metadata URL (e.g., http://<host>:<port>/sap/opu/odata/sap/<service_name>/$metadata).
  
  
  Check Authorization: Ensure that the user executing the action has the necessary authorizations. You can check this in transaction SU53 after the error occurs to see if there are any authorization issues.
  
  
  Activate/Regenerate Service: If the service is not activated, you can activate it in transaction /IWFND/MAINT_SERVICE. If it is already activated, consider regenerating the service to ensure all changes are reflected.
  
  
  Debugging: If the action is implemented but still fails, you may need to debug the backend logic to identify any issues in the implementation.
