• What is the cause and solution for SAP error message /IWBEP/EPM_PRODUCT010 - Orderby is not supported for field &1 ?

  The SAP error message /IWBEP/EPM_PRODUCT010 Orderby is not supported for field &1 typically occurs in the context of OData services when a query is made that includes an orderby clause for a field that does not support sorting. This can happen for various reasons, such as the field being a complex type, a calculated field, or simply not being defined as sortable in the OData service.
  Cause:
  
  Field Type: The field specified in the orderby clause may not be a primitive type (like string, integer, etc.) or may be a complex type that cannot be sorted.
  Service Definition: The OData service may not have defined the field as sortable in its metadata.
  Data Model: The underlying data model may not support sorting for that particular field due to its nature (e.g., it could be a derived or calculated field).
  
  Solution:
  
  Check Field Type: Verify the type of the field you are trying to sort by. Ensure it is a primitive type that can be sorted.
  Review OData Metadata: Check the OData service metadata (usually accessible via a URL like http://<service-url>/$metadata) to see if the field is marked as sortable. If it is not, you may need to modify the service definition.
  Modify Query: If the field is not sortable, consider removing it from the orderby clause or using a different field that is sortable.
  Enhance OData Service: If you have control over the OData service, you may need to enhance it to allow sorting on that field. This could involve modifying the underlying data model or the service implementation.
  Consult Documentation: Refer to SAP documentation or community forums for specific guidance related to the OData service you are using.
  
  Related Information:
  
  OData Services: Understanding how OData services work and how to define fields in the service can help prevent such issues.
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide updates to the OData framework.
  Debugging: If you have access to the backend, consider debugging the OData service to see how it processes the orderby clause and why it fails for the specified field.
  
  By following these steps, you should be able to identify the cause of the error and implement a suitable solution.
