• What is the cause and solution for SAP error message EIT_GW_COMMON010 - Unknown property &1 in entity type &2. ?

  The SAP error message EIT_GW_COMMON010 indicates that there is an issue with an unknown property in an entity type when working with SAP Gateway services. This typically occurs in the context of OData services where the system is unable to recognize a property that is being referenced in the request or response.
  Cause:
  
  Typographical Error: The property name specified in the request might be misspelled or incorrectly referenced.
  Model Mismatch: The property may not exist in the data model defined for the OData service. This can happen if the service has been updated but the client application is still using an older version.
  Service Metadata: The metadata of the OData service might not be properly updated or might not include the property in question.
  Data Model Changes: If there have been recent changes to the underlying data model (e.g., changes in the database or data structure), the OData service may not reflect these changes.
  
  Solution:
  
  Check Property Name: Verify that the property name referenced in your request matches exactly with the property names defined in the OData service metadata. Look for any typographical errors.
  Update Service Metadata: If the service has been modified, ensure that the metadata is updated. You can do this by regenerating the service or refreshing the metadata in the SAP Gateway.
  Check Entity Type: Ensure that the entity type specified in the error message is correct and that it includes the property you are trying to access.
  Test with Service URL: Use the service URL to access the metadata document (usually ending with $metadata) to see the current structure of the OData service and confirm the properties available.
  Clear Cache: If you are using a client application, clear any cached versions of the service to ensure you are working with the latest version.
  Debugging: If you have access to the backend, you can debug the service implementation to see how the properties are being handled.
