• What is the cause and solution for SAP error message /UI2/INTEROP109 - Retrieving a single entry is not supported ?

  The SAP error message /UI2/INTEROP109 Retrieving a single entry is not supported typically occurs in the context of SAP Fiori applications or when using the SAP Gateway. This error indicates that the system is attempting to retrieve a single entry from a data source that does not support this operation. Here are some potential causes, solutions, and related information:
  Causes:
  
  
  Data Source Limitation: The underlying data source (like an OData service) may not be configured to support single entry retrieval. This can happen if the service is designed to return collections of data rather than individual records.
  
  
  Incorrect URL or Request: The request being made to the OData service may be incorrectly formatted, leading the system to interpret it as a request for a single entry when it should be a request for a collection.
  
  
  Service Configuration: The OData service might not be properly configured to handle requests for single entries. This could be due to missing or incorrect annotations in the service definition.
  
  
  Versioning Issues: There may be compatibility issues between the Fiori application and the OData service version being used.
  
  
  Solutions:
  
  
  Check the OData Service: Verify the OData service being called. Ensure that it is designed to support single entry retrieval. You can do this by checking the service metadata in the SAP Gateway.
  
  
  Modify the Request: If the request is incorrectly formatted, modify it to ensure that it requests a collection rather than a single entry. For example, ensure that the URL does not include an identifier that implies a single entry.
  
  
  Service Annotations: If you have access to the service definition, check the annotations and ensure that the service is set up to allow single entry retrieval. You may need to adjust the service implementation.
  
  
  Update or Reconfigure the Service: If the service is outdated or misconfigured, consider updating or reconfiguring it. This may involve regenerating the service or adjusting its settings in the SAP Gateway.
  
  
  Check for Notes and Patches: Look for SAP Notes or patches that may address this specific error. Sometimes, issues are known and documented by SAP, and there may be a recommended fix.
  
  
  Consult Documentation: Review the SAP documentation for the specific Fiori application and OData service you are using. There may be specific requirements or limitations that you need to be aware of.
  
  
  Related Information:
  
  SAP Gateway: Understanding how the SAP Gateway works and how it handles OData services can provide insights into resolving this error.
  Fiori Application Logs: Check the logs for the Fiori application to gather more context about the error. This can help identify the exact point of failure.
