• What is the cause and solution for SAP error message /IWBEP/CM_CP210 - Simple property '&1' not last path segment on select ?

  The SAP error message /IWBEP/CM_CP210 Simple property '&1' not last path segment on select typically occurs in the context of OData services when there is an issue with the way a property is being accessed in a query. This error indicates that the specified property (represented by &1) is not the last segment in the path of the OData request.
  Cause:
  
  
  Incorrect OData Query Structure: The error usually arises when the OData query attempts to access a property that is not the final segment of the entity path. For example, if you have an entity set and you are trying to access a property of that entity in a way that is not compliant with the OData protocol.
  
  
  Navigation Properties: If you are trying to access a navigation property or a complex type property incorrectly, it can lead to this error. The OData service expects the last segment of the path to be a simple property.
  
  
  Service Metadata: The service metadata might not be correctly defined, leading to confusion about which properties are simple properties and which are complex or navigation properties.
  
  
  Solution:
  
  
  Check the OData Query: Review the OData query you are using. Ensure that the property you are trying to access is indeed the last segment of the path. For example, if you are querying an entity set, the query should look something like this:
  /EntitySetName?$select=PropertyName
  Ensure that PropertyName is a simple property and not part of a complex type or navigation property.
  
  
  Review Navigation Properties: If you are trying to access a navigation property, make sure you are using the correct syntax. For example, if you want to access a related entity, you should use:
  /EntitySetName(NavigationProperty=Value)
  followed by the $select for the properties of the related entity.
  
  
  Check Service Metadata: Use the $metadata endpoint of your OData service to review the structure of the entities and their properties. This will help you understand which properties are simple and which are complex or navigation properties.
  
  
  Update the OData Service: If you have control over the OData service, ensure that the service is correctly defined and that the properties are appropriately categorized.
  
  
  Consult Documentation: Refer to the SAP documentation for OData services to ensure compliance with the expected query formats and structures.
  
  
  Related Information:
  
  OData Protocol: Understanding the OData protocol can help in structuring queries correctly. The OData documentation provides guidelines on how to format requests and what is expected in terms of entity relationships.
  SAP Gateway: If you are working with SAP Gateway, familiarize yourself with the specific configurations and settings that might affect how OData services are exposed and consumed.
  Debugging Tools: Use tools like Postman or SAP Gateway Client to test your OData queries and see the responses, which can help in identifying issues with the query structure.
  
  By following these steps, you should be able to resolve the error and successfully access the desired properties in your OData queries.
