  The SAP error message /IWBEP/CM_MGW_RT011 Default value of property '&1' not bound typically occurs in the context of SAP Gateway and OData services. This error indicates that a default value for a property in an OData entity is not properly bound or set, which can lead to issues when trying to access or manipulate data through the OData service.
  Cause:
  
  Missing Default Value: The property in question is expected to have a default value defined in the metadata, but it is not bound correctly in the service implementation.
  Service Implementation Issues: The OData service implementation may not be correctly handling the default values for certain properties.
  Model Configuration: The data model may not be configured correctly, leading to the absence of default values for certain properties.
  Data Annotations: If you are using annotations to define default values, they may not be correctly applied or recognized.
  
  Solution:
  
  Check Metadata: Review the OData service metadata to ensure that the property in question has a default value defined. You can access the metadata by appending $metadata to the service URL.

  Use Annotations: If applicable, use annotations to define default values for properties in your OData service. Ensure that these annotations are correctly recognized by the service.
  Debugging: Use debugging tools to trace the execution of the OData service and identify where the binding of the default value fails.
