KX173 - Details

• The SAP error message KX173 indicates that a characteristic value you are trying to use in a hierarchy is already in use elsewhere in the system. This typically occurs in the context of SAP's classification system or when working with characteristics in a variant configuration scenario.
  
  Cause:
  
  Duplicate Characteristic Value: The characteristic value you are trying to assign is already assigned to another node or level in the hierarchy.
  Hierarchy Structure: The hierarchy structure may not allow for the same characteristic value to be used in multiple places, leading to conflicts.
  Data Integrity: SAP enforces data integrity rules to prevent inconsistencies in the hierarchy, which is why it raises this error.
  
  
  Solution:
  
  Check Existing Hierarchies: Review the existing hierarchy to see where the characteristic value is already being used. You can do this by navigating to the relevant hierarchy in the SAP GUI and checking the nodes.
  Modify the Hierarchy: If the characteristic value is indeed used
