This error message indicates that there is a problem with the ROOTNODE_REF metadata field of a specific entity, which is being attempted to be updated from one value to another.
  Cause:
  
  Inconsistent Data: The error may arise due to inconsistencies in the data model or the underlying database. This can happen if there are changes in the structure of the CDS view or if the data in the database does not match the expected format.

  Check Transport Requests: If the issue arose after a transport, verify that all related objects were transported correctly and that there are no missing dependencies.
  Review Authorizations: Ensure that the user has the necessary authorizations to perform the update. You may need to consult with your security team to verify this.
  Debugging: If the issue persists, consider debugging the process to identify the exact point of failure. This may require technical expertise in ABAP and CDS views.
