• What is the cause and solution for SAP error message /IWBEP/CM_SBMG053 - Cannot extend the model, as all properties are already selected ?

  The SAP error message /IWBEP/CM_SBMG053 indicates that you are trying to extend a model in SAP Gateway, but all properties of the model have already been selected. This typically occurs when you attempt to add additional properties to an existing OData service that has already defined all its properties.
  Cause:
  
  All Properties Selected: The error arises because the model you are trying to extend has already included all its properties, and there is no room to add more.
  Model Configuration: The model might be configured in such a way that it does not allow for further extensions or modifications.
  Service Definition: The OData service definition may have reached its limit in terms of the number of properties that can be selected.
  
  Solution:
  
  
  Review the Model: Check the existing model to confirm which properties are already included. You can do this by examining the service metadata or the model definition in the SAP Gateway Service Builder (transaction code /IWBEP/SEGW).
  
  
  Modify the Model: If you need to add properties, you may need to:
  
  Remove some existing properties if they are not required.
  Create a new entity type or a new model that includes the additional properties you need.
  Ensure that the properties you want to add are not already included in the model.
  
  
  
  Regenerate the Service: After making changes to the model, regenerate the service to ensure that the changes take effect. This can be done in the Service Builder by selecting the service and choosing the "Generate" option.
  
  
  Check for Extensions: If you are trying to extend a standard SAP OData service, ensure that the extension is supported and that you are following the correct procedure for extending standard services.
  
  
  Consult Documentation: Refer to SAP documentation or community forums for specific guidance on extending OData services and handling model properties.
