  The SAP error message GBSE_HANA021 indicates that a hierarchy specified in your query or operation does not exist in the HANA database (HDB). This error typically arises when working with SAP BW (Business Warehouse) or SAP HANA models that utilize hierarchies for data analysis and reporting.
  Cause:
  
  Non-Existent Hierarchy: The hierarchy you are trying to access has not been created or has been deleted.
  Incorrect Hierarchy Name: There may be a typo or incorrect naming in the hierarchy reference.
  Data Model Issues: The hierarchy might not be properly activated or might not be part of the data model you are working with.
  Transport Issues: If the hierarchy was recently transported from another system, it may not have been included or activated correctly in the target system.
  
  Solution:
  
  
  Verify Hierarchy Existence:

  Ensure that the hierarchy name matches exactly with what is being referenced in your query or report.
