• What is the cause and solution for SAP error message /IWBEP/EPM_COMMON035 - Property &1 is not allowed for sorting ?

  The SAP error message /IWBEP/EPM_COMMON035 Property &1 is not allowed for sorting typically occurs in the context of OData services when a property that is not sortable is being requested to be sorted in an OData query. This can happen when the client application (like SAP Fiori or any other OData consumer) tries to sort data based on a property that is either not defined as sortable in the OData service or is not supported for sorting due to the underlying data model.
  Cause:
  
  Non-Sortable Property: The property specified in the error message is not defined as sortable in the OData service metadata. This could be due to the nature of the data (e.g., complex types, calculated fields) or the way the OData service is configured.
  Service Configuration: The OData service might not have been configured to allow sorting on certain properties, either due to business logic or performance considerations.
  Data Model Limitations: Some properties may be derived or calculated fields that cannot be sorted directly.
  
  Solution:
  
  Check OData Metadata: Review the OData service metadata (usually accessible via the $metadata endpoint) to see which properties are marked as sortable. Look for the Sortable attribute in the metadata for the property in question.
  Modify the Query: If the property is indeed not sortable, modify the OData query to remove the sorting on that property. Use only those properties that are allowed for sorting.
  Service Implementation: If you have control over the OData service implementation, consider modifying the service to allow sorting on the property if it makes sense from a business perspective. This may involve changes in the underlying data model or service logic.
  Consult Documentation: Refer to the SAP documentation or the specific OData service documentation for more details on which properties are sortable and any limitations that may apply.
  
  Related Information:
  
  OData Protocol: Understanding the OData protocol and how it handles sorting can provide insights into why certain properties are not sortable.
  SAP Gateway: If you are using SAP Gateway, familiarize yourself with the configuration options available for OData services, including how to define which properties are sortable.
  Performance Considerations: Sometimes, properties are marked as non-sortable to optimize performance, especially if sorting on those properties could lead to inefficient queries or excessive resource consumption.
