• What is the cause and solution for SAP error message GBSE_HANA355 - &1 is not a root hierarchy, provide root hierarchy &2 if needed ?

  The SAP error message GBSE_HANA355 typically indicates an issue related to the hierarchy structure in SAP HANA, particularly when dealing with data models that involve hierarchies. This error suggests that the specified hierarchy is not recognized as a root hierarchy, which is necessary for certain operations or queries.
  Cause:
  
  Non-root Hierarchy: The hierarchy you are trying to use is not defined as a root hierarchy in the system. In SAP, a root hierarchy is the top-level hierarchy that serves as the starting point for any hierarchical structure.
  Incorrect Hierarchy Reference: The hierarchy you are referencing may not be correctly set up or may not exist in the context you are working in.
  Data Model Issues: There may be issues with the data model or the way hierarchies are defined in the underlying data source.
  
  Solution:
  
  Check Hierarchy Definition: Verify that the hierarchy you are trying to use is indeed defined as a root hierarchy. You can do this by checking the hierarchy settings in the SAP HANA modeler or the relevant data source.
  Use the Correct Hierarchy: If the error message suggests a different hierarchy (as indicated by &2), consider using that hierarchy instead. Ensure that you are referencing the correct hierarchy in your queries or data models.
  Hierarchy Configuration: If you have access, review the configuration of the hierarchy in the SAP system. Ensure that it is set up correctly and that all necessary attributes and relationships are defined.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on how to define and manage hierarchies in your specific version of SAP HANA.
  Contact Support: If you are unable to resolve the issue, consider reaching out to SAP support or your internal IT team for assistance. They may have additional insights or tools to diagnose the problem.
  
  Related Information:
  
  SAP HANA Documentation: Check the official SAP HANA documentation for detailed information on managing hierarchies.
  SAP Community: Engage with the SAP Community forums where other users may have encountered similar issues and can provide insights or solutions.
  Training Resources: If you are frequently working with hierarchies in SAP, consider training resources or courses that cover data modeling and hierarchy management in SAP HANA.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
