  The SAP error message GBSE_HANA187, which states "Hierarchy sub-node '&' is a selection variant!", typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when dealing with hierarchies in queries or reports. This error indicates that the system is trying to interpret a hierarchy node as a selection variant, which is not allowed in the context of the operation being performed.
  Cause:
  
  Hierarchy Misconfiguration: The hierarchy node being referenced may not be properly configured or may not exist in the context of the query.
  Selection Variant Misuse: The system is interpreting a hierarchy node as a selection variant due to incorrect settings or usage in the query.
  Data Model Issues: There may be issues with the underlying data model, such as missing or incorrect relationships between nodes in the hierarchy.
  
  Solution:
  
  
  Check Hierarchy Configuration: 
  
  Verify that the hierarchy is correctly defined in the data model. Ensure that all nodes are properly configured and that the hierarchy is active.
  Check if the node referenced in the error message exists in the hierarchy.
  
  
  
  Review Query Settings:
  
  If you are using a query in SAP BW, check the query settings to ensure that the hierarchy is being used correctly. Make sure that the hierarchy is selected as a characteristic and not as a selection variant.
  Ensure that the query is not trying to filter or select data using a hierarchy node that is not valid.
  
  
  
  Adjust Selection Variants:
  
  If you are using selection variants, ensure that they are set up correctly and do not conflict with the hierarchy settings.
  Review any selection criteria in the query to ensure they are appropriate for the hierarchy being used.
  
  
  
  Test with Different Nodes:
  
  Try using different nodes in the hierarchy to see if the error persists. This can help identify if the issue is specific to a particular node.
