• What is the cause and solution for SAP error message /IWBEP/CM_EQ023 - orderby is not supported ?

  The SAP error message /IWBEP/CM_EQ023 orderby is not supported typically occurs in the context of OData services when a query is made that includes an orderby clause that is not supported by the underlying data model or the OData service implementation.
  Cause:
  
  Unsupported Fields: The fields specified in the orderby clause may not be supported for sorting in the OData service. This can happen if the fields are not part of the entity's metadata or if they are calculated fields that cannot be sorted.
  Data Model Limitations: The underlying data model may not support sorting on certain fields due to performance considerations or because they are not indexed.
  Service Implementation: The OData service may not have been implemented to handle sorting for specific fields or entities.
  
  Solution:
  
  Check Metadata: Review the OData service metadata (usually accessible via the $metadata endpoint) to ensure that the fields you are trying to sort by are indeed part of the entity and are marked as sortable.
  Modify Query: If the fields are not sortable, modify your query to remove the orderby clause or to use only those fields that are supported for sorting.
  Service Implementation: If you have control over the OData service implementation, consider updating the service to support sorting on the required fields. This may involve modifying the service's data provider class or the underlying database queries.
  Consult Documentation: Refer to the SAP documentation for the specific OData service you are using to understand its limitations and capabilities regarding sorting.
  
  Related Information:
  
  OData Version: Ensure that you are aware of the OData version being used, as different versions may have different capabilities and limitations.
  SAP Notes: Check for any relevant SAP Notes that may address this issue or provide guidance on best practices for implementing OData services.
  Performance Considerations: Be mindful of performance implications when enabling sorting on large datasets, as it can lead to increased load times and resource consumption.
