• What is the cause and solution for SAP error message /IWBEP/EPM_BP024 - Orderby is not supported for &1 ?

  The SAP error message /IWBEP/EPM_BP024 Orderby is not supported for &1 typically occurs in the context of OData services when a client attempts to use the $orderby query option on an entity or property that does not support ordering. This can happen for various reasons, such as:
  Cause:
  
  Unsupported Property: The property specified in the $orderby clause may not be defined as sortable in the OData service metadata.
  Entity Type Limitations: The entity type itself may not support ordering due to its design or the underlying data model.
  Data Type Restrictions: Certain data types may not support ordering operations, leading to this error.
  Service Configuration: The OData service may not be configured to allow ordering on specific fields or entities.
  
  Solution:
  
  Check Metadata: Review the OData service metadata (usually accessible via the $metadata endpoint) to confirm which properties support ordering. Look for the OrderBy annotation in the metadata.
  Modify Query: Adjust your OData query to remove the $orderby clause or change it to a property that is supported for ordering.
  Service Configuration: If you have control over the OData service, consider modifying the service implementation to allow ordering on the desired properties. This may involve changes in the underlying data model or service logic.
  Consult Documentation: Refer to the SAP documentation for the specific OData service you are using to understand its limitations and capabilities regarding ordering.
  
  Related Information:
  
  OData Protocol: Understanding the OData protocol and its query options can help in constructing valid queries.
