  The SAP error message /IWBEP/SBOD111 Entity Type '&1' defines more than one author property typically occurs in the context of SAP Gateway and OData services. This error indicates that the entity type defined in your OData service has multiple properties marked as "author" properties, which is not allowed. An author property is typically used to indicate the creator or owner of a record, and there should only be one such property per entity type.
  Cause:
  
  Multiple Author Properties: The entity type in question has been defined with more than one property that is marked as an author property. This can happen due to incorrect configuration or design of the data model.
  Model Definition Issues: If you are using a data model that has been generated or modified, it might have inadvertently included multiple author properties.
  
  Solution:
  
  Check Entity Type Definition: Review the definition of the entity type in the data model. Look for properties that are marked as author properties.
  Remove Duplicate Author Properties: Ensure that only one property is designated as the author property. You can do this by:
  
  Accessing the data model in the SAP Gateway Service Builder (transaction code SEGW).
  Navigating to the entity type in question.
  Checking the properties and ensuring that only one is marked as an author property.
  
  
  Regenerate the Service: After making the necessary changes, regenerate the OData service to ensure that the changes take effect.
  Test the Service: Once the changes are made, test the OData service to confirm that the error has been resolved.
