• What is the cause and solution for SAP error message /IWBEP/CM_CP213 - Empty select property information is not allowed ?

  The SAP error message /IWBEP/CM_CP213 Empty select property information is not allowed typically occurs in the context of OData services when there is an issue with the metadata or the way the service is defined. This error indicates that there is an attempt to define a select property in an OData query without providing the necessary information, which is not allowed.
  Cause:
  
  Empty Select Property: The error is triggered when a select property is defined in the OData service but does not have any associated fields or properties. This can happen if the service is incorrectly configured or if there are issues in the underlying data model.
  Incorrect OData Query: The client may be sending a request that includes an empty select statement, which is not valid.
  Service Definition Issues: There may be issues in the service definition or the way the entity types and properties are defined in the metadata.
  
  Solution:
  
  
  Check OData Query: Review the OData query being sent to ensure that the $select parameter is not empty. If it is, either remove it or provide valid property names.
  Example of a valid $select:
  /YourService/Entity?$select=Property1,Property2
  
  
  Review Service Metadata: Check the service metadata to ensure that all entity types and properties are correctly defined. Make sure that there are no empty select properties in the service definition.
  
  
  Update Service Implementation: If you are developing the OData service, ensure that the implementation correctly handles the select properties. If a property is not supposed to be selectable, it should not be included in the metadata.
  
  
  Debugging: If you have access to the backend, you can debug the OData service to see how the select properties are being processed. This can help identify where the empty property is being introduced.
  
  
  Consult Documentation: Refer to the SAP documentation for OData services to ensure that you are following best practices in defining and consuming OData services.
  
  
  Related Information:
  
  OData Protocol: Understanding the OData protocol and how it handles queries, including $select, $filter, and other query options, can help in troubleshooting issues.
  SAP Gateway: If you are using SAP Gateway, familiarize yourself with the tools and transaction codes (like /IWFND/MAINT_SERVICE) that can help you manage and troubleshoot OData services.
  SAP Community: Engaging with the SAP Community or forums can provide insights from other users who may have encountered similar issues.
  
  By following these steps, you should be able to resolve the error and ensure that your OData service functions correctly.
