  The SAP error message /IWFND/CM_CNP049 (Success) typically indicates that there is a successful response from the OData service, but it may not be what the user expected. This message is often related to the consumption of OData services in SAP Gateway and can arise in various scenarios, such as when the service is called but does not return the expected data or when there is a mismatch in the expected output.
  Cause:
  
  Service Configuration Issues: The OData service might be configured incorrectly, leading to unexpected results.
  Data Availability: The data that the service is supposed to return may not be available or may not meet the criteria specified in the request.
  Query Parameters: The parameters sent in the request may not match the expected format or values, leading to a successful call but with no relevant data returned.
  Authorization Issues: The user may have the necessary permissions to call the service, but the data returned may be restricted based on authorization settings.
  
  Solution:
  
  Check Service Configuration: Ensure that the OData service is correctly configured in the SAP Gateway. This includes checking the service definition and the associated data model.
  Validate Data Availability: Verify that the data you are trying to access through the OData service exists in the backend system. You can do this by directly querying the database or using transaction codes like SE11 or SE16.
  Review Query Parameters: Double-check the parameters being sent in the request. Ensure they are correctly formatted and valid for the service being called.
  Authorization Check: Ensure that the user has the necessary authorizations to access the data. You can check this in the user roles and authorizations assigned to the user.
  Debugging: If the issue persists, consider debugging the OData service to trace the execution and identify where the data retrieval might be failing.
