This error typically arises in the context of data modeling or when trying to access certain data entities in the SAP S/4HANA environment.
  Cause:
  
  Incorrect BO Structure: The Business Object structure may not be defined correctly, leading to the absence of a root entity.

  Solution:
  
  Check the CDS View Definition: Review the CDS view definition to ensure that the root entity is correctly defined. Look for the @ObjectModel.root annotation, which specifies the root entity.
  Validate Annotations: Ensure that all necessary annotations are present and correctly configured in the CDS view. This includes checking for any missing or incorrect references to entities.
  Review Data Model: If there have been recent changes to the data model, verify that the root entity still exists and is correctly linked to the other entities in the BO structure.
  Authorization Check: Ensure that the user has the necessary authorizations to access the root entity. This can be checked in the user roles and authorizations assigned to the user.
