  Cause:
  This error typically arises due to one of the following reasons:

  Incorrect Configuration: There may be a misconfiguration in the way annotations are defined in your CDS (Core Data Services) views or in the OData service.

  Check for Inheritance: If you are using inheritance in your data model, ensure that annotations are not being inherited in a way that causes duplicates.
